Question

2CrO₄²⁻(aq) + 2H⁺(aq) ⇌ Cr₂O₇²⁻(aq) + H₂O(l)

Write the equation for the equilibrium constant (K) of the reaction studied in this exercise.

Answer 1

The equation for the equilibrium constant is K = [Cr₂O₇²⁻] * [H₂O(l)] / [2CrO₄²⁻] * [2H⁺(aq)]. The equilibrium constant measures the extent of the reaction at equilibrium.

Step-by-step explanation:

The equation for the equilibrium constant (K) of the reaction studied in this exercise is:

K = [Cr₂O₇²⁻] * [H₂O(l)] / [2CrO₄²⁻] * [2H⁺(aq)]

The equilibrium constant (K) is a measure of the extent to which the reactants are converted into products at equilibrium. In this equation, the concentrations of the species in the reaction are represented by square brackets. The equilibrium constant can be calculated using the concentrations of the species at equilibrium.
