In which of the following equilibrium \[{{K}_{c}}\] and \[{{K}_{p}}\] are not equal?                [AIPMT (S) 2010]

A)  \[2NO(g){{N}_{2}}(g)+{{O}_{2}}(g)\]

B)  \[S{{O}_{2}}(g)+N{{O}_{2}}(g)S{{O}_{3}}(g)+NO(g)\]

C)  \[{{H}_{2}}(g)+{{I}_{2}}(g)2HI(g)\]

D)  \[2C(s)+{{O}_{2}}(g)2C{{O}_{2}}(g)\]

Correct Answer: D

Solution :

Key Idea The reaction for which the number of moles of gaseous products () is not equal to the number of moles of gaseous reactantshas different value of Kc and Kp.
