Which one of the following conditions will favour maximum formation of the product in the reaction
A_2(g) + B_2(g) ⇌ X_2(g) , $$\Delta $$_rH = –X kJ ?

The equilibrium constants of the following are

N₂ + 3H₂ $$\rightleftharpoons$$ 2NH₃;     K₁

N₂ + O₂ $$\rightleftharpoons$$ 2NO;     K₂

H₂ + $${1 \over 2}$$O₂ $$\rightleftharpoons$$ H₂O;     K₃

The equilibrium constant (K) of the reaction :

2NH₃ + $${5 \over 2}$$ O₂ $$\rightleftharpoons$$ 2NO + 3H₂O will be

A 20 litre container at 400 K contains CO_2(g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). The volume of the container is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of CO₂ attains its maximum value, will be

(Given that : SrCO_3(s) $$\rightleftharpoons$$ SrO_(s) + CO_2(g), K_p = 1.6 atm)

Consider the following liquid-vapour equilibrium.
Liquid $$\rightleftharpoons$$ Vapour
Which of the following relations is correct ?
