Question

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? the direction of the chemical equilibrium will shift to the right, favoring the forward reaction. the chemical equilibrium will not be affected by an increase in temperature. the direction of the chemical equilibrium will shift to the left, favoring the reverse reaction. the chemical equilibrium will be lost permanently with a change of temperature.

Explanation:

This is an endothermic reaction as heat is on the reactant - side. According to Le - Chatelier's principle, increasing the temperature for an endothermic reaction will shift the equilibrium in the direction that absorbs the heat, which is the forward reaction.

Answer:

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