For the following reactions, equilibrium constants are given :

S(s) + O₂(g) ⇋ SO₂(g); K₁ = 10⁵²

2S(s) + 3O₂(g) ⇋ 2SO₃(g); K₂ = 10¹²⁹

The equilibrium constant for the reaction,

2SO₂(g) + O₂(g) ⇋ 2SO₃(g) is :

In a chemical reaction,


the initial concentration of B was 1.5 times of the concentration of A, but the equilibrium concentrations of A and B were found to be equal. The equilibrium constant (K) for the aforesaid chemical reaction is -

Two solids dissociate as follows –

The total pressure when both the solids dissociated simultaneously is -

Consider the reaction
N₂(g) + 3H₂(g) $$\rightleftharpoons$$ 2NH₃(g)

The equilibrium constant of the above reaction is K_p. If pure ammonia is left to dissociate, the partial pressure of ammonia at equilibrium is given by (Assume that P_NH3 << P_total at equilibrium)
