Choose the answer that most correctly explains why changing the temperature causes a shift in equilibrium? Changing temperature cannot affect the equilibrium of a reaction. Changing temperature will have an unequal effect on the rates of the forward and reverse reactions based on their frequency factors. Changing temperature will always have a greater effect on the forward reaction rate than on the reverse reaction rate. Changing temperature will have an unequal effect on the rates of the forward and reverse reactions based on their activation energies.

Changing temperature will have an unequal effect on the rates of the forward and reverse reactions based on their activation energies.

Explanation:

Lowering or increasing the temperature of the reaction will cause it to either be an endothermic or exothermic reaction, which are the names for reactions where heat is absorbed (former) and reactions where heat is released (latter) with the products. This shift in temperature will also change the value of the equilibrium constant.

This change in constant value is what causes the unequal effect on the rates of the forward and reverse reactions.
