In what direction will the equilibrium shift when heat is removed?

The reaction will remain unchanged. The reaction will shift to produce both reactants and products. The reaction will shift to produce products. The reaction will shift to produce reactants.

Explanation / Answer

According to Le Chatelier's Principle, when stress is applied to a system at equilibrium. the system tends to adjust itself so as to minimise the change.

Part A: When the amount of NH3 gas is increased then the equilibrium will shift towards the left side that is to the reactants side to reduce the concentration of product and maintain the equilibrium.

Hence, the correct option is 'the reaction will shift to produce reactants'.

Part B: When heat is added to an endothermic reaction at equilibrium then the equilibrium will shift to that direction where the heat is absorbed. The heat is absorbed at the forward reaction that is towards the right side which increases the concentration of products.

Hence, the correct option is 'the reaction will shift toward the products'.

Part C: When the concentration of H2 gas is reduced in the equilibrium mixture, then the reaction shifts towards the left side to increase the concentration H2 gas and this decreases the concentration of products.

Hence, the correct option is 'the reaction will shift toward the reactant'.

Part D: When heat is removed from an exothermic reaction at equilibrium then the reaction will shift towards the forward direction that is to the product side, to adjust the effect and to be in equilibrium.

Hence, the correct option is 'the reaction will shift towards the product'.
