In chemical kinetics, the reaction order is the exponent to which the concentration of a reactant is raised in the rate law equation. For a general reaction
Comparing the initial rate of reaction across several experiments with varying starting concentrations.
v=k[A]p[B]qv equals k open bracket cap A close bracket to the p-th power open bracket cap B close bracket to the q-th power The order with respect to a specific reactant. Global Order ( ): The sum of the partial orders ( Key Methods to Determine the Order of Reaction
