In which of the following reaction Kp > Kc

A.N2 + 3H2 2 NH3
B.H2 + I2 2HI
C.PCl3 + Cl2 PCl5✓ Correct
D.2 SO3 O2 + 2SO2.
Explanation

According to the formula, g Δn P C K = K RT Hence, for option (a) 2 P C P C K K RT ,K K For option (b) 0 P C P C K K RT ,K =K For option (c) 1 P C P C K K RT , K K For option (d) 1 P C P C K K RT ,K K So, option (d) is the correct answer.
