In a sealed flask at constant temperature, the equilibrium

\mathrm{2NO(g) + O_2(g) \rightleftharpoons 2NO_2(g)}

has

K_p = 6.0\times10^1

. The system is initially at equilibrium. A small amount of

\mathrm{O_2(g)}

is removed, and immediately afterward

Q_p

is found to be

9.0\times10^1

. As equilibrium is reestablished, what shift occurs?
