The reaction is endothermic now

i.e it involves decomposition. So decrease in pressure favours d forward reaction which is d intermittent production of PCl3

The more the number of molecules of a substance the more the pressure.

The reactant has one mole and the products has a combination of two moles as a result the pressure of the products is higher than that of the reactant.

A reduction in pressure will cause the equilibrium to shift to the right in order to increase pressure what this means is that a decrease in pressure will increase the formation of the products or will favor the forward reaction.

Note this only applies to gases.

Pressure doesn't affect the equilibrium of solids.

No the answer is B. Decrease in pressure will increase the yield of pcl3
