Consider the following equilibrium in a vessel 

${\text{NH}}_{\text{4}}\text{HS}\left(\text{s}\right)\rightleftharpoons {\text{NH}}_{\text{3}}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{S}\left(\text{g}\right)$

The incorrect statement(s) among the following is/are

Addition of catalyst at constant temperature increases the value of  ${\text{K}}_{\text{c}}$

Addition of inert gas at constant volume shifts the equilibrium in the forward direction

Addition of ${\text{NH}}_{\text{4}}\text{HS}$  at equilibrium increases the value of ${\text{K}}_{\text{c}}$ , at constant temperature

Addition of catalyst at constant temperature increases the value of  ${\text{K}}_{\text{p}}$
