MCQ
process  ${N_{2\left( g \right)}} + 3{H_{2\left( g \right)}} \rightleftharpoons 2N{H_3}_{\left( g \right)} + heat$ 
  • A
    $K_p = K_c$
  • B
    $K_p = K_c\, (RT)^{-1}$
  • $K_p = K_c\, (RT)^{-2}$
  • D
    $K_p = K_c\, (RT)$

Answer

Correct option: C.
$K_p = K_c\, (RT)^{-2}$
c
The correct option is $C$

$K_P=K_C(R T)^{-2}$

For the reaction, $\Delta n=2-(1+3)=-2$, hence the correct relation would be $K_p=K_C(R T)^{-2}$
