The equilibrium constant, also known as K, is a measure of how far a chemical reaction proceeds towards completion. It is the ratio of the concentrations of products to reactants at equilibrium.
The equilibrium constant is calculated by taking the concentration of the products, raised to the power of their coefficients in the balanced chemical equation, divided by the concentration of the reactants raised to the power of their coefficients.
A slower reaction at K=1 indicates that the concentrations of products and reactants are equal at equilibrium. This means that the reaction is proceeding at a slower rate and has not reached completion.
Temperature affects the equilibrium constant by shifting the equilibrium in favor of either the products or reactants. An increase in temperature favors the endothermic reaction, while a decrease in temperature favors the exothermic reaction.
Yes, the equilibrium constant can change if there is a change in temperature, pressure, or concentration of reactants or products. However, it will remain constant at a given temperature and pressure.
