Why: experimental data is typically in concentration vs. time. How: integrate the expression of rate law k k k k differential rate expression integrated rate. Half the problems you do in kinetics use this differential rate expression. The rate law of a reaction does not have to correspond to the stoichiometry of a reaction. I will be providing a handout and worksheet on all the ways to determine Using calculus, the differential rate law for a chemical reaction can be integrated with respect to time to give an equation that relates the amount of reactant or rate = k[N2O5]. This equation is called the rate expression or rate law. and k is called the rate constant. Suppose you have a single reactant, such as you would What is the rate law expression for this reaction? Solution: 1) compare exp. 1 and exp. 3. A remains constant and B is tripled. The rate from 1 to 3 remains The differential rate law shows how the rate of the reaction changes with concentration of reactants (and sometime products). The integrated rate law, which is derived by means of calculus from the differential rate law, shows how the concentration of reactant changes with time. We will look at the form of the integrated rate law for a first order reaction, and in the next worksheet we will extend this to discuss the idea of half life.

is called the differential rate law. The differential expressions can be integrated to give an explicit relation of \(\ce{[A]}\) with respect to time t. These explicit relations are called integrated rate laws. Depending on the value of n, the integrated equations are different. Solving Kinetics Problems Involving Differential Rate Law Chemical kinetics is the study of the speed or rate of a chemical reaction under various conditions. Collisions must occur in order for chemical reactions to take place. These collisions must be of sufficient energy to make and break bonds. Rate Laws of Reactions Worksheet: 1.
