Question

Consider the chemical reaction in equilibrium.

H2 + I2 + heat mc006-1.jpg 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.

Answer 1

"A. The direction of the chemical equilibrium will shift to the right, favoring the forward reaction. " is the correct answer

Answer 2

The correct option is A.
The chemical equation given above is an endothermic reaction. An endothermic reaction is a type of reaction which absorb heat from the environment. An endothermic reaction needs heat to occur, therefore, increasing the temperature of such a reaction will favor the formation of more product and the equilibrium of the reaction will shift [forward] to the right, which is the product side.
