Question

According to the law of mass action, what is the correct expression for the equilibrium constant for the reaction 2a b⇋3c?

Answer 1

The equilibrium constant expression for the reaction 2A + B ⇋ 3C is Keq = ( [C]^3 ) / ( [A]^2 * [B] ). It uses the equilibrium concentrations of the substances A, B, and C with the coefficients in the balanced chemical equation as exponents.

Step-by-step explanation:

The equilibrium constant expression for the reaction 2A + B ⇋ 3C is given by:

Keq = ( [C]^3 ) / ( [A]^2 * [B] )

Here, [A], [B], and [C] represent the equilibrium concentrations of substances A, B, and C, respectively.

In this expression, the coefficients of the reactants and products in the balanced chemical equation are used as exponents to represent the stoichiometry of the reaction.
