The Equilibrium Constant for the Following Reaction Becomes Larger as the Temperature

Multiple Choice

The equilibrium constant for the following reaction becomes larger as the temperature at which the reaction is run increases.

2 NOCl(g) 2 NO(g) + Cl₂(g)   K_c = 5.6 x 10^-6 at 400 K
What does this tell us about the reaction?

A) Heat is given off in the reaction.
B) Heat is absorbed in the reaction.
C) Heat is neither given off nor absorbed in the reaction.
D) Increasing the amount of NOCl would also increase the equilibrium constant for the reaction.
E) Increasing the amount of NO would also increase the equilibrium constant for the reaction.
