MCQ
For the reaction $PCl_5\,(g)  \rightleftharpoons  PCl_3\, (g) + Cl_2\, (g)$ The two reaction constants $K_p$ and $K_c$ are related to each other by the expression
  • ✓
    $\log \frac{{{K_p}}}{{{K_c}}} - \log RT = 0$
  • B
    ${K_p}(RT) = {K_c}$
  • C
    ${K_p} = {K_c}{\left( {RT} \right)^{ - 1}}$
  • D
    None of the above
✓

Answer

Correct option: A.
$\log \frac{{{K_p}}}{{{K_c}}} - \log RT = 0$
a
$\Delta {n_g} = 1,\,\,\,{k_p} = {k_c}{\left( {RT} \right)^{ - 1}}$
