What is the initial rate of reaction?

The initial rate of a reaction is the instantaneous rate at the start of the reaction (i.e., when t = 0). The initial rate is equal to the negative of the slope of the curve of reactant concentration versus time at t = 0.

Also asked, why do we use initial rates of reaction?

The rate decreases as the reacants are used up. The initial rate is measured as this is the fastest rate and the only time that you actually KNOW the concentrations of the reactants. This is because the reaction is rapid and the substrate concentration quickly declines.

Why kinetics are important?

Much of our study of chemical reactions is concerned with the formation of new substances from a given set of reactants. However, it is equally important to understand how rapidly chemical reactions occur. The area of chemistry that is concerned with the speeds, or rates, of reactions is called chemical kinetics.

Why is the rate law important?

The rate of a chemical reaction is, perhaps, its most important property because it dictates whether a reaction can occur during a lifetime. Knowing the rate law, an expression relating the rate to the concentrations of reactants, can help a chemist adjust the reaction conditions to get a more suitable rate.
