Introduction:
Reaction order is an important parameter in chemical kinetics that describes the relationship between the concentration of reactants and the rate of a chemical reaction. Reaction order can be determined experimentally by measuring the rate of reaction as the concentration of one or more reactants is varied. The reaction order can then be used to develop mathematical models that describe the behavior of the reaction.
Understanding reaction order
The reaction order of a chemical reaction is determined by the rate law, which is an equation that relates the rate of the reaction to the concentrations of the reactants. The rate law is determined experimentally by measuring the rate of reaction as the concentration of one or more reactants is varied while holding the concentrations of the other reactants constant.
The reaction order of a reactant is the exponent in the rate law that corresponds to the concentration of that reactant. For example, if the rate law for a reaction is given by:
rate = k[A]^2[B]^1
then the reaction order with respect to A is 2, and the reaction order with respect to B is 1.
The overall reaction order is the sum of the individual reaction orders with respect to each reactant. In the example above, the overall reaction order would be 3.
Using a reaction order calculator
A reaction order calculator is a tool that can be used to calculate the reaction order of a chemical reaction. There are several online calculators available that can perform this calculation, and they typically require input of the rate law equation and the concentrations of the reactants.
One example of a reaction order calculator is the online tool provided by the University of Oregon. This calculator allows the user to input the rate law equation, the concentrations of the reactants, and the units of measurement. The calculator then calculates the reaction order with respect to each reactant, as well as the overall reaction order.
Another example of a reaction order calculator is the one provided by Sigma-Aldrich. This calculator also allows the user to input the rate law equation and the concentrations of the reactants, and it provides the reaction order with respect to each reactant as well as the overall reaction order.
