Document Summary
Experimentally, it has been found that a reaction rate depends on the concentrations of certain reactants as well as the concentration of catalyst, if there is one. The rate of this reaction is observed to be proportional to the concentration of nitrogen dioxide. When the concentration of nitrogen dioxide is doubled, the rate doubles. The rate is also proportional to the concentration of fluorine; doubling the concentration of fluorine also doubles the rate. A rate law is an equation that relates the rate of a reaction to the concentrations of reactants (and catalyst) raised to various powers rate constant, is a proportionality constant in the relationship between rate and concentrations. Once you know the rate law for a reaction and have found the value of the rate constant, you can calculate the rate of a reaction for any values of reactant concentrations. Keep in mind that the rate constant is dependent upon temperature.
