Chemistry - Chemical Equilibrium Question with Solution | TestHub

In option$\left(\mathrm{B}\right)-\mathrm{\Delta }{\mathrm{n}}_{\mathrm{g}}$is$-$ve therefore, increase in pressure will bring reaction in forward direction.

In option$\left(\mathrm{C }\right)-$as the reaction is exothermic therefore, increase in temperature will decrease the equilibrium constant.

In option$\left(\mathrm{D }\right)-$Equilibrium constant changes only with temperature.

Hence, option$\left(\mathrm{B}\right),\mathrm{ }\left(\mathrm{C}\right)$and$\left(\mathrm{D}\right)$are correct. Therefore, option$\left(\mathrm{A}\right)$is incorrect choice.
