15. CO2 can be hydrogenated into methanol through flowing a gas mixture (molar ratio between
H2 and CO2 = 3) into a catalyst bed at 1 bar. It is an exothermic reaction whose equation is
shown below. Choose the incorrect statement.
CO2(g)+3H2(g)→CH3OH(g)+H2O(g)
(A) The yield of methanol cannot reach 100% given any reaction condition.
(B) The extent of reaction (ξ) at equilibrium can be increased by pressurizing the reactor.
(C) Adding an inert gas into the mixture at fixed pressure will reduce ξ at equilibrium.
(D) Decreasing reaction temperature increases ξ at equilibrium.
(E) The equilibrium conversion can be calculated by solving Keg =ξ2 (4-2ξ)2/(3-3ξ)3
