First-Order Integrated Rate Law

Definition

The first-order integrated rate law describes how the concentration of reactants in a chemical reaction changes over time when the reaction order is one.

Related terms

Zero Order Reaction: A type of chemical reaction where changing the concentration of reactants doesn't affect the rate at which products are formed.

Pseudo First Order Reaction: A complex reaction that behaves like a first-order reaction because one reactant is present in such large quantities that its concentration hardly changes during the course of the reaction.

Arrhenius Equation:

An equation that gives the dependence of the rate constant 'k' of a chemical reaction on temperature and activation energy.
