The equilibrium constant, Keq, is defined as the ratio of the concentrations of products to reactants. What is the equilibrium constant for the following reaction:
ClNO2 (g) + NO (g) ↔ NO2 (g) + ClNO (g)
Tell me your problem here. Do you know how to write the Keq expression? It tells you in the problem what Keq is.
ncos
To find the equilibrium constant, Keq, for the given reaction, we need to express it in terms of the concentrations of the products and reactants.
The equilibrium constant expression is given by:
Keq = [NO2] * [ClNO] / [ClNO2] * [NO]
Here, [NO2], [ClNO], [ClNO2], and [NO] represent the molar concentrations of the respective substances at equilibrium.
To determine the equilibrium constant, you will need to know the concentrations of the reactants and products at equilibrium. The concentrations can be expressed in terms of molarity (mol/L) or any other convenient unit of concentration.
Once you have the values for the concentrations of ClNO2, NO, NO2, and ClNO at equilibrium, substitute them into the equilibrium constant expression and calculate the value of Keq.
Please note that the concentrations must be for the substances at equilibrium. If you are not given the concentrations directly, you will need additional information, such as the initial concentrations and any changes that occurred during the reaction, to determine the equilibrium concentrations.
Remember, the equilibrium constant is temperature-dependent, and the units of Keq will depend on the stoichiometry of the balanced equation and the units used for concentration.
