how to determine the rate constant

Kinetic data may be analysed to determine the reaction rate, orders with respect to each reactant, and the rate constant for the reaction As we shall see, these 

Sample Exercise 14 6 Determining a Rate Law from Initial Rate Data that we know both the rate constant and the reaction orders, we can use the rate law with  

➢ Determine the rate law and rate constant for a reaction from a series of experiments given the measured rates for various concentrations of reactants ➢ Use the 

the concentrations of reactants and the rate of a reaction with these concentrations, we can determine the rate constant 5 4 x 10-7 M/s = k (0 0100M )(0 200M)

The first is to establish, experimentally, the rate law which describes the kinetic observations The second is to determine a mechanism (molecular model) which is 

From which we can write and equilibrium expression, calculate free energy changes This rate constant converts chemical concentrations into reaction rates

The simplest example is when one concentration is doubled while the others are held constant • measure initial rates for two different concentrations of every
