Question

Describe a method which can be used to determine the order of a first order reaction.

Answer 1

The integrated rate law method can be used to determine the order of a first-order reaction.

\[\ce{A -> Products}\]

Assume the order of the reaction is n. The rate law (also known as differential rate law) of the response can be written as follows:

Rate = k [A]ⁿ

Calculus can be used to turn the differential rate law into an integrated version. Integrated rate equations accommodate for the variation in reactant concentrations over time, making them more convenient. Integrating differential rate laws for distinct reactions yields various expressions.
