Consider the following endothermic reaction: CH4(g) + H2O(g) > CO(g) + 3H2(g) at equilibrium. How will the equilibrium be affected by increasing temperature and pressure?

Since the reaction is endothermic, by increase in temperature,  endothermic reaction increases, forward reaction increases, production of CO & H2 increases.
Since there is a change in volume from 2 mol reactants to 4 mol products , by increasing pressure, the reaction towards less volume increases, backward reaction increases, production of CH4 & H2O increases.
