WebThe order of reaction determines the relationship between the rate of reaction and the concentration of reactants or products. It is the power to which a concentration is raised … A common form for the rate equation is a power law: The constant is called the rate constant. The exponents, which can be fractional, are called partial orders of reaction and their sum is the overall order of reaction. In a dilute solution, an elementary reaction (one having a single step with a single transition state) is empirically found to obey the law of mass action. This predicts that the rate depends only on t…
