3O₂(g) $$\rightleftharpoons$$ 2O₃(g)

for the above reaction at 298 K, K_c is found to be 3.0 $$\times$$ 10^$$-$$59. If the concentration of O₂ at equilibrium is 0.040 M then concentration of O₃ in M is

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)
