Chemistry · EQUILIBRIUM
हिन्दीConsider the following statements regarding chemical equilibrium and catalysts: (A) A catalyst lowers the activation energy for both the forward and reverse reactions by the same amount. (B) A catalyst changes the equilibrium constant \( K \) of the reaction. (C) A catalyst alters the equilibrium composition of a reaction mixture. (D) In the Contact process, \( \text{V}_2\text{O}_5 \) is used to increase the rate of oxidation of \( \text{SO}_2 \) to \( \text{SO}_3 \). Which of the above statements are correct?
Correct answer · Option 1
(A) and (D) only
Explanation
A catalyst lowers activation energy of both forward and reverse reactions equally and does not alter the equilibrium composition or equilibrium constant. Statements (A) and (D) are correct.
