Question

The relation between $K_P$ and $K_C$ for the reaction $\text{A}\left(\text{g}\right)\text{+B}\left(\text{g}\right)\rightleftharpoons \text{C}\left(\text{g}\right)\text{+2D}\left(\text{g}\right)$ is-

• A. $K_P=K_C{\left[RT\right]}^{-1}$
• B. $K_P.K_C^{-1}=RT$
• C. $K_C{K}_P^{-1}=RT$
• D. $K_P=K_C{\left[RT\right]}^3$

Answer 1

Answer: (B)

${\text{Δn}}_{\text{g}}\text{=}$ (No. Moles of products- No. of moles of reactant) $=1$
${\text{Δn}}_{\text{g}}\text{=}\text{1}$
$\text{Kp}\text{=}{\left[{\text{K}}_{\text{c}}\right]}^{{\text{Δn}}_{\text{g}}}\text{RT}$
