For the reaction PC l_5 _ (g) PC l_3 _ (g) + C l_2 _ (g) - Vidyadip

MCQ

For the reaction $PC{l_5}_{(g)}$ $\rightleftharpoons$ $PC{l_3}_{(g)} + C{l_2}_{(g)}$

A
${K_p} = {K_c}$
B
${K_p} = {K_c}{(RT)^{ - 1}}$
✓
${K_p} = {K_c}(RT)$
D
${K_p} = {K_c}{(RT)^2}$

✓

Answer

Correct option: C.

${K_p} = {K_c}(RT)$

(c) $\Delta n =2-1=1$

${K_p} = {K_c}(RT)$
