The correct option is B both 1 and 2
When the pressure on the system is increased, the volume decreases proportionately. The total number of moles per unit volume increases. According to Le-Chatelier's principle, the equilibrium shift in the direction in which there is decrease in number of moles. If there is no change in number of moles of gases in a reaction, a pressure change does not affect the equilibrium.
If the temperature at equilibrium is increased reaction will proceed in the direction in which heat can be used. Thus increase in temperature will favour the forward reaction for endothermic reaction.
Similarly, increase in temperature will favour the backward reaction in exothermic reactions.
