Borek said:What are you trying to calculate? Thread subject says "calculating equilibrium constants" yet Keq is given.
The equilibrium constant Keq is a measure of the ratio of products to reactants at a specific temperature which indicates the extent to which a chemical reaction will proceed to reach equilibrium.
The equilibrium constant Keq is calculated by taking the ratio of the concentrations of the products to the concentrations of the reactants, each raised to their respective stoichiometric coefficients as shown in the chemical equation.
The numerical value of Keq indicates the relative concentrations of products and reactants at equilibrium. A larger Keq indicates a greater concentration of products and a higher likelihood of the reaction proceeding to completion, while a smaller Keq indicates a lower concentration of products and a lower likelihood of the reaction proceeding to completion.
The equilibrium constant Keq is affected by changes in temperature. An increase in temperature will cause an increase in Keq for an endothermic reaction (heat is a reactant) and a decrease in Keq for an exothermic reaction (heat is a product).
The numerical value of the equilibrium constant Keq is determined by the nature of the chemical reaction and the temperature. Therefore, it cannot be altered without changing the conditions of the reaction. However, the equilibrium position (the relative concentrations of products and reactants) can be shifted by changing the concentration of reactants or products, or by changing the temperature or pressure of the system.
