How is the effect of concentration changes on the reaction rate seen in the rate law?A.The rate law does not show how concentration changes would affect the reaction rate.B.A change in concentration of a reactant would change the exponent of that reactant.C.The effect of concentration changes on the rate constant affects the reaction rate.D.The exponents determine how much concentration changes affect the reaction rate.SUBMITarrow_backPREVIOUS

How does the rate law equation effectively describe the relationship between the rate of a chemical reaction and the concentration of reactants?

The rate constant of a first order reaction is 4×10−3sec−1 .At a reactant concentration of 0.02 M, the rate of reaction would be:
