this equilibrium reaction needs the following answered :

PCl5 (g) ↔ PCl3 (g) + Cl2 (g) DH0 = 87.9 kJ

How will the following affect the above equilibrium?
a) increasing the concentration of PCl5
b) decreasing the concentration of Cl2
c) increasing the temperature
d) increasing the size of the reaction vessel
e) adding a catalyst

- use le chateliers principle for the first 4 parts (If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change)

-for part e, adding catalyst does not affect equilibrium, it only affects the rate by providing alternate pathway for the reaction to occur with a lower activation energy
