In which of these gas-phase equilibria is the yield of productsincreasedbyincreasing the total pressure on the reaction mixture?: 2SO3(g) ⇌ 2SO2(g) + O2(g) PCl5(g) ⇌ PCl3(g) + Cl2(g ) 2NO(g) + Cl2(g) ⇌2NOCl(g) CO(g) + H2O(g) ⇌ CO2(g) + H2(g)

in # 2NO_((g)) + Cl_(2(g)) ⇌2NOCl_((g)) #


In above equation, the number of moles of reactants is greater than product.So, the volume is also lesser.According to Le Chatelier's principle, when pressure of a gaseous reaction is increased, it moves in direction where its volume decreases.

And so the reaction favours product thus increasing its yield
