The reaction rate constant may be defined as the rate of the reaction when theconcentration of each reactants is ___________a) Zerob) Unityc) Doubled the initial concentrationd) Infinite

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:

What must be known for the rate constant to be calculated from the rate law?A.The reaction rate at known product concentrationsB.The temperature at the beginning of the reactionC.The reaction rate at known reactant concentrationsD.The activation energy the reaction must overcome

For a reaction with rate equation Rate = k[A][B][C]², how would the rate change if the concentration of reactant C is doubled while the concentrations of reactants A and B remain unchanged?Select one:a.The rate would be halved.b.The rate would quadruple.c.The rate would double.d.The rate would remain unchanged.

What happens to the reaction rate as the reactants get used up in a reaction?A.The rate of the reaction stays constant until the reactants are gone.B.The rate of the reaction begins to decrease as reactants are used up.C.The rate of the reaction increases steadily as products are formed.D.The rate of the reaction is not affected by the concentration of reactants.SUBMITarrow_backPREVIOUS

Rate constant of a zero order reaction does not depend upon the concentration of thereactant
