CO(g) +2 H2 (9) 2 CH3OH(g) K = 2.2 x 104 at 298 k %3D A stoichiometric mixture of CO(9) and H2 (g) was allowed to react in two different 2.0 L rigid containers at a constant temperature of 298 K. The reaction is represented by the equation above. Diagram 1 represents the uncatalyzed reaction and diagram 2 represents the catalyzed reaction one hour after the reactants were mixed. Which of the following correctly explains the experimental results represented in the particle diagrams? S Although the reaction is thermodynamically favorable because AG° 0 based on the value of K, but the addition of a catalyst improved the orientation of the reactants during collisions, allowing the catalyzed reaction to proceed in one hour. The reaction is not thermodynamically favorable because AG° > 0 based on the value of K, but the catalyzed reaction could proceed in one hour because it has a lower AH and a higher AS.
