1.	Volume of the flask in which species are transferred is double of the earlier flask. In which of the following cases, equilibrium will be shifted in the forward direction ?A. `N_(2)(g)+3H_(2)(g)hArr 2NH_(3)(g)`B. `N_(2)(g)+O_(2)(g)hArr 2NO(g)`C. `PCl_(5)(g) hArr PCl(g)+Cl_(2)(g)`D. `2NO(g)hArrN_(2)(g)+O_(2)(g)`
Answer» Correct Answer - C As volume is doubled, the pressure is reduced to one-half. Under these conditions, the equilibrium involving increase in the number of moles of gaseous components in the forward direction will be shifted forward. Thus, eqm. `PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g)` will be shifted in the forward direction.
