Vedclass · Answer

(C) According to Le Chatelier's principle: $1$. For an endothermic reaction $(\Delta H > 0)$,high temperature favors the forward reaction (higher yield). $2$. For a reaction where the number of moles of gaseous products is less than the number of moles of gaseous reactants $(\Delta n_g < 0)$,high pressure favors the forward reaction. Analyzing the options: - Option $A$: Endothermic $(\Delta H > 0)$,$\Delta n_g = (1+3) - 1 = +3$. High temperature helps,but high pressure does not. - Option $B$: Exothermic $(\Delta H < 0)$,$\Delta n_g = 2 - (1+3) = -2$. High pressure helps,but high temperature does not. - Option $C$: Endothermic $(\Delta H > 0)$,$\Delta n_g = 2 - (1+2) = -1$. High temperature helps,and high pressure helps. - Option $D$: Exothermic $(\Delta H < 0)$,$\Delta n_g = (2+7) - 2 = +7$. Neither high temperature nor high pressure helps. Therefore,option $C$ is the correct answer.

In which of the following reactions are high temperature and high pressure favorable for obtaining a higher yield of products?
