In which of the following equilibrium Kc and Kp are not equal? (AIPMT 2010) (a) 2C s O g 2CO g (b) 2NO g N g O g p K (c) SO g NO g SO g NO g (d) H g I g 2HI g

According to the formula, g Δn P C K = K RT Here, For option (a) 1 P C K = K (RT) For option (b) 0 P C P C K = K (RT) ;K = K For option (c) 0 P C P C K = K (RT) ;K = K For option (d) 0 P C P C K = K (RT) ;K = K Hence, option (a) is the correct answer.
