Vedclass · Answer

(C) The given reaction is $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$ with $\Delta H = -198.2 \, kJ/mol$.$1$. Effect of Pressure: The reaction involves a decrease in the number of moles of gas ($3$ moles of reactants to $2$ moles of product). According to Le Chatelier's principle,high pressure favors the side with fewer moles,so high pressure increases the yield of $SO_3$.$2$. Effect of Temperature: The reaction is exothermic $(\Delta H $3$. Effect of Concentration: Increasing the concentration of reactants ($SO_2$ and $O_2$) shifts the equilibrium to the right,increasing the yield of $SO_3$.Therefore,high pressure,low temperature,and high concentration of reactants favor the maximum yield of $SO_3$.

Which of the following conditions will favor the maximum yield of $SO_3$ according to Le Chatelier's principle for the reaction: $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$ $(\Delta H = -198.2 \, kJ/mol)$?
