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.

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

The forward reaction absorbs heat. It is endothermic. Going in that direction will remove heat from the system. The temperature of the system will drop.

The reverse reaction produces heat. It is exothermic. Converting products back to reactants will adds to the heat of the system. The temperature of the system will increase.

By the Le Chatelier's Principle, a system in equilibrium will respond to changes in a way that minimizes their effect.

In this question, the change is an increase in temperature. The system will seek to reduce its temperature. It will favor the forward reaction, which is endothermic and removes heat from the system.

Temperature of the system will decrease. There will be more products and less reactants. The equilibrium will shifts to the left.

c, liquids evaporate, creating a gas
