Effect of a Catalyst on Equilibrium moles of substance A catalyst changes the mechanism of a reaction to one with a lower activation ti energy. A catalyst has no effect on the condition of equilibrium.
But does affect the rate at which equilibrium ffect he hich quilibrium is attained. Which of the following k statements is correct? CO(g) 3H2 (g) CH4 (g) H 2O(g) k 1. At equilibrium the reaction stops. 3
