Question

What is the numerical value of K, for the reaction if the concentrations at equilibrium are [SO2] = 0.10 M, [02] = 0.08 M, and [SO:] = 0.66 M?

Answer 1

The value of the equilibrium constant, K, for the given reaction is 3.7.

Step-by-step explanation:

The value of the equilibrium constant, K, for the reaction 2SO₂(g) + O₂(g) = 2SO₃(g), can be calculated using the concentrations at equilibrium.

The equilibrium constant expression for this reaction is K = [SO₃]² /([SO₂]²[O₂]).

Substituting the given equilibrium concentrations, we have K = (1.1)² / ((0.90)²(0.35)). Calculating this expression gives us K = 3.7.
