Which statement is true? The rate of appearance of products of a chemical reaction is always equal to the rate of disappearance of reactants. If a reaction follows a second-order rate law; it must have two steps in its reaction mechanism. The half-life for a first-order reaction is always larger than the half-life for a second-order reaction; The half-life for a first-order reaction is independent of the initial concentration of the reactant: The half-life for a second-order reaction is independent of the initial concentration of the reactant:
