Significance of rate law
WebSep 28, 2015 · The exponents in a rate law describe the effects of the reactant concentrations on the reaction rate and define the reaction order. Consider a reaction for which the rate law is: \[\ce{rate}=k[A]^m[B]^n \nonumber \] If the exponent m is 1, the … WebaA + bB ⇌ cC + dD. According to the law of mass action, the constant value obtained by relating equilibrium concentrations of reactants and products is called the equilibrium constant. For the forward reaction, this is given by. K c = [ C] c [ D] d [ A] a [ B] b. The equilibrium constant for the reverse reaction is the inverse of the forward ...
