Question

The equilibrium constant, K_c, for the following reaction is 9.80×10^-3 at 1090 K.

2SO₃(g) 2SO₂(g) + O₂(g)

When a sufficiently large sample of SO₃(g) is introduced into an evacuated vessel at 1090 K, the equilibrium concentration of O₂(g) is found to be 0.226 M.

Calculate the concentration of SO₃ in the equilibrium mixture.

Expert Solution

Step 1

Kc: It is the equilibrium constant and it is defined as the ratio of the product of the concentration of products to the product of the concentration of reactants raise to their stoichiometric coefficients.

For example,

A + B ⇌ C +D

Kc = $\frac{[C] [D]}{[A] [B]}$
