Question

Match the reactions in the List I with the units of the equilibrium constant in the List II.

Answer 1

A) $CaC{O}_3\left(s\right)\rightleftharpoons CaO\left(s\right)C{O}_2\left(g\right)$

$K_c=\left[C{O}_2\right]$

Unit = mol$L^{-1}$

$K_p=PC{O}_2$

Unit = atm

B) $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$

$K_c=\frac{\left[C{l}_2\right]\left[PC{l}_3\right]}{[PC{l}_5}$

Unit = mol$L^{-1}$

$K_p=\frac{PC{l}_2{P}_{p}C{l}_3}{PC{l}_5}$

Unit = atm

C) $K_c=\left[HI{]}^2/\right[I_2\left]\right[H_2]$

Unit atm

D) $K_c=\left[N{H}_3{]}^2/\right[H_2{]}^3\left[N_2\right]$
