Integrated Rate Law
The equation obtained by integrating a differential rate law, giving concentration directly as a function of time.

In depth
Integrated rate laws let the order be determined from a single experiment by finding which plot — concentration, its logarithm, or its reciprocal against time — gives a straight line. They also allow the concentration remaining at any future time to be predicted directly.
Examples in the real world
A linear ln[A] against t plot confirms first order and gives k directly from the gradient.
