In which of the following system, doubling the volume of the container cause a shift to the right

A.H2(g) + Cl2(g) 2HCl(g)

B.2CO(g) + O2(g) 2CO2(g)

C.N2(g) + 3H2(g) 2NH3(g)

D.PCl5(g) PCl3(g) + Cl2(g)✓ Correct

Explanation

Increase in volume can shift reaction in that direction on which no. of moles are more. 5 3 2 PCl PCl Cl
