The dissociation of phosgene,which occurs according to the reaction $COCl_{2(g)} \rightleftharpoons CO_{(g)} + Cl_{2(g)}$,is an endothermic process. Which of the following will increase the degree of dissociation of $COCl_2$?

For the reaction $CO_{(g)} + H_2O_{(g)} \rightleftharpoons CO_{2(g)} + H_{2(g)}$ at a given temperature,the equilibrium amount of $CO_{2(g)}$ can be increased by

When $NaNO_3$ is heated in a closed vessel,$O_2$ is liberated and $NaNO_2$ is left behind. At equilibrium,

In which of the following reactions does the yield of the product not increase by the application of high pressure?

The gas phase reaction $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)}$ is an exothermic reaction. The decomposition of $N_2O_4$ in an equilibrium mixture of $NO_{2(g)}$ and $N_2O_{4(g)}$ can be increased by:

Consider the equilibrium $CO_{(g)} + 3H_{2(g)} \rightleftharpoons CH_{4(g)} + H_2O_{(g)}$. If the pressure applied over the system increases by two-fold at constant temperature,then which of the following statements are correct?
$(A)$ Concentration of reactants and products increases.
$(B)$ Equilibrium will shift in the forward direction.
$(C)$ Equilibrium constant increases since the concentration of products increases.
$(D)$ Equilibrium constant remains unchanged as the concentration of reactants and products remain the same.
