Question

At constant temperature, the equilibrium constant (K_p) for the decomposition reaction: N₂O₄ ⇌ 2NO₂ is expressed by
K_p = (4x²P) / (1-x²), where P = total pressure at equilibrium, x = extent of decomposition. Which one of the following statements is true?

Prashant Kotian · Accepted Answer

Correct answer: D. The equilibrium constant K_p depends only on the temperature of the system. Changing pressure or extent of decomposition shifts the equilibrium but does not alter the value of K_p. Therefore, correct answer is D.
