For this question, we're told that a reaction is being run under standard conditions, and that the equilibrium constant for this reaction is much greater than 1. With this information in mind, we can find the correct answer without even having to resort to math. Since the equilibrium constant is greater than one, we know that the products of this reaction are favored over the reactants. And since the products are favored, this means that the reaction must be shifted to the right, in which case it is spontaneous. It's important to know that a spontaneous reaction will always have a negative change in Gibb's energy.

For completion's sake, however, we can show that the Gibb's free energy change is negative by utilizing the free energy change equation.

From this equation, we can see that if  is greater than one (as it is in the reaction for this question) the natural logarithm of this value will also be positive. And since the ideal gas constant and the absolute temperature are also positive values, the product of all these values will be positive. But, there is a negative sign in front of these terms, hence making our final answer negative.

In this question, we're being asked to provide a circumstance that will never result in a spontaneous reaction. In other words, which answer choice presents a situation that will always be non-spontaneous.

To evaluate the spontaneity of a reaction, it's essential to look at the change in the Gibb's free energy of that reaction. A negative change results in a spontaneous reaction, whereas a positive change results in a non-spontaneous reaction.

We can see that each of the answer choices mentions enthalpy and entropy. Therefore, we need to be able to relate these two terms with the Gibb's free energy term. To do this, we can make use of the following expression.

Again, in order to have a non-spontaneous reaction, the  term shown above needs to have a positive value.

From the above expression, we can conclude that any process that has a positive  and a negative  will always be positive, and hence will always result in a non-spontaneous reaction.

A reaction is spontaneous when Gibb's free energy is negative. As a result, we need to determine the temperature range where Gibb's free energy is less than zero. Since we know the values for changes in enthalpy and entropy, we can plug them into the Gibb's free energy equation, and set it equal to zero.

437K is the temperature at which Gibb's free energy is zero. Since entropy is positive for this reaction, increasing the temperature will result in a more negative value for Gibb's free energy.

As a result, any temperature that is greater than 437K will make this reaction spontaneous.

The second law of thermodynamics states that the entropy of the system and the entropy of the surroundings is equal to the entropy of the universe. The rest of the answer choices are not one of the fundamental laws of themodynamics.

First law of thermodynamics states that the energy of the universe is always constant. This is called the conservation of energy. The total energy of the universe is defined as follows:

According to the law, energy gained or lost by a system is reciprocated by its surroundings. This means that energy, such as heat energy, lost by the system will be gained by the surroundings. This will keep the total energy constant. Energy can be converted from one form to another (such as from kinetic to potential); however, it cannot be created or destroyed.

The second law of thermodynamics states that the disorder of the universe is always increasing. As mentioned, energy can never be created, nor destroyed. In an exothermic reaction, heat energy is transferred from the system to the surroundings. In an endothermic reaction, heat energy is transferred from the surroundings to the system. 

Entropy is a measure of disorder; therefore, a substance with low entropy will be highly ordered. Gases have the highest entropy because the molecules are spread far apart and are more chaotic. Solids, on the other hand, have the least entropy because they are typically found in an ordered, lattice structure with very little chaos. A freezing reaction involves conversion of a liquid to a solid; therefore, the product of this reaction will have the lowest entropy.

The third law of thermodynamics states that a perfect crystal at absolute zero ( or ) has an entropy of zero (lowest possible entropy). Note that entropy can never be less than zero.

Microstates are microscopic configurations of a substance, and relates directly to the entropy of the system. The more microstates, the higher the entropy. Since this substance has the lowest entropy it will have the least amount of microstates.

To understand the relationship between Gibbs free energy and enthalpy, we need to look at the following equation:

Here,  is change in Gibbs free energy,  is enthalpy,  is change in entropy, and  is the temperature in Kelvin. From the given information, we know that both temperature and entropy are zero; therefore, Gibbs free energy equals the enthalpy for this substance.

In order to solve this problem, we'll need to break it up into steps.

Step 1: Calculate the amount of energy necessary to raise the sample of ice from  to . To do this, we'll need to use the following equation:

Step 2: Calculate the amount of energy necessary to convert the sample at  from ice to water. We'll need to make use of the following equation:

Step 3: Calculate the amount of energy necessary to convert the sample of water from  to .

Step 4: Sum the amount of energy from the previous 3 steps. This value is the total amount of energy for the entire process.

Step 5: Now that we know the total amount of energy needed for the process, we need to calculate the time based on the amount of power provided.
