Vedclass · Answer

(D) According to Le Chatelier's principle: $1$. For an exothermic reaction (indicated by $+ Q$),the reaction is favoured at low temperature. $2$. For the pressure effect,we compare the number of moles of gaseous products and reactants. Reactants: $1 + 1 = 2$ moles. Products: $2 + 1 = 3$ moles. Since the number of moles of products $(3)$ is greater than the number of moles of reactants $(2)$,the reaction is favoured at low pressure to shift the equilibrium towards the side with more moles.

The gaseous reaction $A(g) + B(g) \rightleftharpoons 2C(g) + D(g) + Q$ is most favoured at
