Consider the reaction, `A(g)+2B(g)hArr 2D(g)+3E(g)+` heat and state how the following changes at equilibrium will affect the yield of the product. D(g)-
some amount of D(g) is added to the reaction system, keeping temperature and volume constant.

Explanation

At constant temperature and volume, if some amount of D(g) [product] is added to the reaction system at equilibrium, then, according to Le Chatelier's principle, the equilibrium will shift to the left. As a result, the yield of D(g) will decrease. however, the concentration of D(g) at the new equilibrium will be greater than that at the original equilibrium.
