Question

(i) $AgI\left(s\right)\rightleftharpoons {Ag}^{+}\left(aq\right)+I^{-}\left(aq\right)$
(ii) $CaO\left(s\right)+{CO}_2\left(g\right)\rightleftharpoons Ca{CO}_3\left(s\right)$
(iii) ${Br}_2\left(l\right)\rightleftharpoons {Br}_2\left(g\right)$
Equilibrium expression for them can be written as:

Answer 1

(i) $K_c=\left[{Ag}^{+}\right(aq\left)\right]\left[I^{-}\right(aq\left)\right]$
(ii) $K_p=\frac{1}{P_{{CO}_2}};K_C=\frac{1}{\left[{CO}_2\right(g\left)\right]}$
(iii) $K_p=P_{{Br}_2}\left(g\right);K_C=\left[{Br}_2\right(g\left)\right]$
