Which of the following statement is/are true of rate law?
1) The proportionality constant k, called the rate constant, and n, called the order of the reactant in the rate law, must be determined by experiment.
2) The concentrations of the products of a chemical reaction do not appear in the rate law.
3) The order of a reactant in the rate law can only be a positive integer.

Question

1) This statement is true because the rate constant and order of reactants must be determined experimentally through the method of initial rates or other methods.
2) This statement is also true because the rate law only includes the concentrations of the reactant(s) that are involved in the rate-determining step, not the products.
3) This statement is false because the order of a reactant in the rate law can be any real number, not just a positive integer.
