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

What effect does the concentration of reactants have on the rate of a reaction?A.Increasing the concentration decreases the rate of the reaction.B.Changing the concentration has no effect on the reaction rate.C.The effect of concentration on rate varies within the reaction.D.Increasing the concentration increases the rate of the reaction.SUBMITarrow_backPREVIOUS

How are the concentration of the reactants and reaction rate related?A.The concentration of reactants is a result of the reaction rate.B.Increasing concentration increases all reaction rates the same.C.Increasing concentration decreases all reaction rates the same.D.A change in concentration results in a change in the rate of a reaction.

The reaction rate isMultiple choice question.the rate at which reactants are reformed in the reverse reaction.constant for any one chemical reaction.the rate at which reactants are changed into products.impossible to measure.

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
