Question

The equilibrium will be shifted in the opposite direction if: P C l3(g)+C l2(g) P C l5(g) (A)  PCl3 is added (B) helium gas is added (C) catalyst is added (D) pressure is reduced

underset1 text mole PCl 3(g)+ underset1 text mole Cl 2(g) underset1 text mole PCl 5(g) In the backward reaction number of moles increases, hence, decreasing pressure will favour the backward reaction.

Q. The equilibrium will be shifted in the opposite direction if: $PC l_{3} (g) + C l_{2} (g) PC l_{5} (g)$

$PC l_{3}$ is added

helium gas is added

catalyst is added

pressure is reduced

$1 mole PC l_{3} (g) + 1 mole C l_{2} (g) 1 mole PC l_{5} (g)$
In the backward reaction number of moles increases, hence, decreasing pressure will favour the backward reaction.

Q. The equilibrium will be shifted in the opposite direction if: PCl3​(g)+Cl2​(g)PCl5​(g)

PCl3​ is added
