Chemistry - Chemical Equilibrium Question with Solution | TestHub

At high temperature, the following reaction occurs
$4\mathrm{C}\mathrm{u}\mathrm{O}\left(\mathrm{s}\right)\rightleftharpoons 2\mathrm{C}{\mathrm{u}}_2\mathrm{O}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$
Consider the following statements regarding reaction
$1.$${\mathrm{K}}_{\mathrm{p}}={\mathrm{p}}_{{\mathrm{O}}_2}$
$2.$${\mathrm{K}}_{\mathrm{p}}$depends upon the amounts of CuO and$\mathrm{C}{\mathrm{u}}_2\mathrm{O}$
$3.$${\mathrm{K}}_{\mathrm{p}}<<{\mathrm{K}}_{\mathrm{c}}$
$4.$${\mathrm{K}}_{\mathrm{p}}>{\mathrm{K}}_{\mathrm{c}}$
