Consider the chemical reaction in equilibrium.

H2 + I2 + heat ⬄ 2HI

What will happen to the chemical equilibrium if the temperature of the system is increased?

A) The direction of the chemical equilibrium will shift to the right, favoring the forward reaction.

B) The chemical equilibrium will not be affected by an increase in temperature.

C) The direction of the chemical equilibrium will shift to the left, favoring the reverse reaction.

D) The chemical equilibrium will be lost permanently with a change of temperature.

This is an application of Le Chatlier's principle: What happens when we add a reagent to one side of an equation? The reaction will shift to the other side. So heat is a reactant and we're adding more of it, the reaction must therefore, shift to the right (or the products side).
