Calculate the value of Keq for this reaction at equilibrium.
2NOCl(g) ↔2NO(g) + Cl2(g)
To calculate the value of Keq for a reaction at equilibrium, we need to use the concentrations of the reactants and products at equilibrium.
Let's say we have the following concentrations at equilibrium:
[NOCl] = x
[NO] = 2x
[Cl2] = x
The balanced equation tells us that the stoichiometric coefficients are in a ratio of 2:2:1, meaning that the equilibrium expression is:
Keq = ([NO]^2 * [Cl2]) / [NOCl]^2
Substituting the equilibrium concentrations into the equation:
Keq = ((2x)^2 * x) / (x^2)
Keq = (4x^2 * x) / (x^2)
Keq = 4x^3 / x^2
Keq = 4x
Since we don't know the actual value of x, we cannot calculate the exact value of Keq. However, the expression for Keq is 4x, indicating that the value of Keq will depend on the concentration of the species at equilibrium.
