In which one of the following gaseous equilibria, p K is less than c K ? (CMC LUDHIYANA 2010) (a) N O 2NO (b) 2SO O 2SO (c) 2HI H I (d) N O 2NO

Here, according to the formula, g Δn P C K = K RT For option (a) 1 P C P C K = K (RT) ;K > K For option (b) -1 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 (b) is the correct answer.
