MCQ

In which of the following $K_p$ is less than $K_c$ ?

A
${N_2}{O_4}\, \rightleftharpoons \,2N{O_2}$
B
$2HI\, \rightleftharpoons \,{H_2} + {I_2}$
✓
$2S{O_2} + {O_2}\, \rightleftharpoons \,2S{O_3}$
D
${N_2} + {O_2}\, \rightleftharpoons \,2N{O}$

✓

Answer

Correct option: C.

$2S{O_2} + {O_2}\, \rightleftharpoons \,2S{O_3}$

c
${K_p} = {K_c}{(RT)^{\Delta n}}$ $\Delta n\, = \, - \,1$ $\therefore \,\,{K_p} = \,\frac{{{K_c}}}{{RT}}$
