Write the equilibrium expression for the following:
2NOCl (g) ==== 2 NO + Cl2 (g)
It's the product of the right side over the product of the left side and each coefficient becomes an exponent for that substance.
The equilibrium expression for the given reaction is:
Kc = [NO]^2 * [Cl2] / [NOCl]^2
Where [NO] represents the concentration of NO, [Cl2] represents the concentration of Cl2, and [NOCl] represents the concentration of NOCl at equilibrium.
To write the equilibrium expression for the given reaction, we need to express the concentrations of the reactants and products. The equilibrium expression is written based on the stoichiometric coefficients of the balanced equation.
The balanced equation is: 2NOCl (g) ⇌ 2NO (g) + Cl2 (g)
The equilibrium expression is written as follows:
Kc = [NO]^2 * [Cl2] / [NOCl]^2
Here, [NO] and [Cl2] are the molar concentrations of nitrogen monoxide and chlorine gas, respectively. [NOCl] is the molar concentration of nitrogen monochloride (nitrosyl chloride).
The equilibrium constant (Kc) represents the ratio of product concentrations to reactant concentrations at equilibrium. It provides information about the position of the equilibrium and the relative concentrations of the reactants and products.
