Answer» Solution :(i) Rate LAW. The EXPRESSION in which reaction rate is given in terms of molar concentration of the reactants with each term raised to some power , Which mayor may not be same as the stoichiometric coefficient of the reaction species in a balanced chemical equation. `xA+yBrarr` products Rate `=k[A]^m[B]^n` k = Rate constant (ii) Rate constant : for a reaction involving the reactants A and B. Reaction rate = `=k[A]^m[B]^n` the constant k is CALLED rate constant of the reaction. If `[A] = 1M and [B] = 1M,`Reaction rate = k Thus, the rate constant (k) of a reaction is equal to the rate of reaction when the concentration of each reactant is equal to 1 mol `L^(-1)` . The change in the concentration of reactant product per unit TIME under the condition of unit nation of all the reactant. |
