Rate law and reaction order experimental determination of rate laws next tutorial relationship between reaction concentrations and time show all questions. The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reaction orders). The expressions used to describe these relationships are called rate laws or rate equations suppose this reaction obeys a first-order rate law: r = k [a].Download
