Change in volume of the system does not alter the number of moles in which of the following equilibriums :
A
N2(g) + O2(g) 
2NO(g)
B
PCl5(g) PCl3(g) + Cl2(g)
C
N2(g) + 3H2(g) 2NH3(g)
D
SO2Cl2(g) SO2(g) + Cl2(g)
Answer
N2(g) + O2(g) 2NO(g)
Explanation
Solution
In this reaction the ratio of number of moles of reactants to products in same i.e., 2 : 2, hence change in volume will not alter the number of moles .
