(B) The given reaction is $C_2H_4(g) + H_2(g) \rightleftharpoons C_2H_6(g)$ with $\Delta H = -32.7 \ kcal$.Since $\Delta H$ is negative,the reaction is exothermic.According to Le Chatelier's principle,for an exothermic reaction,a decrease in temperature shifts the equilibrium in the forward direction.Therefore,reducing the temperature will increase the yield and equilibrium concentration of the product $C_2H_6$.
