For an exothermic reaction, what effect will increasing the temperature have on the equilibrium? (a) there will be a shift toward the products. (b) there will be a shift toward the reactants. (c) there will not be a shift in equilibrium. (d) not enough information is given.

Option (B) is the correct answer.

Explanation:

According to Le Chatelier's principle, any disturbance caused in the equilibrium reaction will shift the equilibrium in a direction that oppose the change or disturbance.

As the given reaction is exothermic in nature. So, when we increase the temperature then more heat will be releasing on product side. Therefore, equilibrium will shift in a direction where there will be less heat or low temperature.

Hence, equilibrium will shift in the backward direction.

Thus, we can conclude that for an exothermic reaction, increasing the temperature on the equilibrium will be a shift toward the reactants.
