• # question_answer 98) In which of the following equilibrium ${{K}_{c}}$and ${{K}_{p}}$are not equal? A)  $2C(s)+{{O}_{2}}(g)2C{{O}_{2}}(g)$ B)  $2NO(g){{N}_{2}}(g)+{{O}_{2}}(g)$ C)  $S{{O}_{2}}(g)+N{{O}_{2}}(g)S{{O}_{3}}(g)+NO(g)$ D)  ${{H}_{2}}(g)+{{l}_{2}}(g)2Hl(g)$

${{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta {{n}_{g}}}}$ $\Delta {{n}_{g}}\ne 0$for the reaction $2C(s)+{{O}_{2}}(g)2C{{O}_{2}}$ Thus, ${{K}_{p}}\ne {{K}_{c}}$
