Explanation :
a) if temperature decreases for endothermic reaction , the reaction shift to left.
b) if volume decreases , then the reaction shift to few number of moles of gas side.
c) some PCl5 is removed , then reaction shift to left.
e) if inert gas is added at constant pressure , volume is increase . so reaction shift to more number of moles of gas
