1.

For the reversible reaction, N_(2) (g) + 3 H_(2) (g) hArr 2 SO_(3) (g) The equilibrium shifts in the forward direction

Answer»

by increasing the CONCENTRATION of `NH_(3)`
by decreasing the pressure
by decreasing the pressure
by decreasing the concentration of `N_(2) (g) and H_(2)` (g)

Solution :As forward reaction is accompanied by decrease in the number of moles, applying Le Chatelie'rs principle , increses of pressure will shift the equilibrium in the forward DIRECTION, Also , as forward reaction is exothermic , increases of TEMPERATURE will shift the equilibrium in the forward direction .
