What is the rate of a reaction and how can you determine it experimentally?

The rate of a reaction is the rate at which reagents are used up and product are formed. Reaction rates depend on concentration. A typical rate law is rate=k*[A]m*[B]n. To find the values of m and n we will keep the value of [B] constant and plot [A] vs t (time). If the plot is linear then the order with respect to A is 0, so m=0. If this is not the case, we plot ln[A] vs t. If the plot is linear then it is a first order with respect to A and m=1. If neither of these happen we plot 1/[A] vs t. If the plot is linear than we have a second order reaction with respect to A and m=2. The same method is applied to find out the value of n.

Potassium Chlorate(VII) decomposes to produce Potassium Chloride and Oxygen. Using the following data calculate the enthalpy change of this decomposition: Enthalpy of formation(KClO4) = -430 kJ mol-1, Enthalpy of formation(KCl) = -440 kJ mol-1
