JEE MAIN - Chemistry (2002 - No. 8)
Change in volume of the system does not alter which of the following equilibria?
N2(g) + O2(g) $$\leftrightharpoons$$ 2NO (g)
PCl5(g) $$\leftrightharpoons$$ PCl3 (g) + Cl2 (g)
N2(g) + 3H2(g) $$\leftrightharpoons$$ 2NH3 (g)
SO2Cl2 (g) $$\leftrightharpoons$$ SO2 (g) + Cl2 (g)
Explicação
In this reaction the ratio of number of moles of reactants to products is same $$i.e.\,\,2:2,$$ hence change in volume will not alter the number of moles.
