Question

A 3.5 L container at equilibrium contains 1.25 mole of SO2, 0.35 mole NO2, 0.55 mole NO, and 2.3 mole SO3. What is the equilibrium constant

Answer 1

The equilibrium constant (K) for the given reaction can be calculated using the concentrations of the reactants and products at equilibrium.

Step-by-step explanation:

The equilibrium constant, represented as K, is determined by the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. In the given reaction: SO2 (g) + NO2 (g) → SO3 (g) + NO (g), the equilibrium constant can be calculated as follows:

K = [SO3] * [NO] / [SO2] * [NO2]

Using the given concentrations: [SO2] = 1.25 mole, [NO2] = 0.35 mole, [NO] = 0.55 mole, and [SO3] = 2.3 mole, the equilibrium constant can be calculated as:

K = (2.3 * 0.55) / (1.25 * 0.35)

K ≈ 1.48
