WebThe equilibrium constant, K, describes the relative amounts of reaction species at equilibrium. The expression for K is equal to the concentrations (or partial pressures) of the products raised to their stoichiometric coefficients divided by the concentrations (or partial pressures) of the reactants raised to their stoichiometric coefficients. WebThe differential equation that describes the mathematical dependance of rate of reaction on the concentration terms of the reactants is called rate law or rate expression or rate equation. For a general reaction, aA + bB + cC ----------> products. the rate law can be written as: rate (r) = k [A] x [B] y [C] z. where.
