Define Rate equation/ Rate law / Rate expression

Rate equation/ Rate law / Rate expression
  • The Rate equation of the reaction gives the relationship between reaction rate and concentrations
  • The algebraic equation that relates the rate of  reaction(-rA )to the concentration of species participating in the reaction is called the rate law for the reaction
  • For reaction
a A + b B +......... r R + s S +...........
  • The rate law can be written as


  • Where 
                -r= rate of reaction
                  k = rate constant/ reaction rate constant/specific reaction rate
                 CA , CB......= Concentrations of A, B......
                  nA, nB.......= power of the concentrations of reactants A, B.......
