explanation:
moles of reactants = 2
moles of products = 2 + 1 = 3
2 -----------> 3
when pressure increases reaction shifts to reverse direction as less number of moles side
when pressure decreases reaction shifts to forward direction as more number of moles side
here pressure decreases so the reaction shifts to more moles side that is products side and moles Cl2 is formed
