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

Explanation: Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

This is a type of Endothermic reaction because heat is absorbed in the reaction.

On increasing the temperature, according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease in temperature occurs. As this is an endothermic reaction, the temperature is decreasing in forward direction as heat is being absorbed.

Thus on increasing the temperature the reaction will shift in the right and rate of forward direction will increase.
