Equilibrium Quiz-2

For the reaction, $CO(g) + Cl_2(g)\rightleftharpoons COCl_2(g)$ the value of $K_p /K_c$ is equal to :

A definite amount of solid $NH_4SH$ is placed in a flask already containing $NH_3$ gas at certain temperature and 0.50 atm pressure. $NH_4SH$ decomposes to give $NH_3$ and $H_2S$ and total equilibrium pressure in flask is 0.84 atm. The equilibrium constant for the reaction is:

For a polyprotic acid say $H_3PO_4,$ its three dissociation constant $K_1,K_2,$ and $K_3$ are in the order

For the reaction $CaCO_3(s)\rightleftharpoons CaO(s) + CO_2(g),$ the pressure of $CO_2(g)$ depends on

The concentration of a pure solid or liquid phase is not included in the expression of equilibrium constant because
