This is an equation that relates the rate of a chemical reaction to the concentrations of its reactants.

First-Order Reaction:

This is a type of chemical reaction where the rate depends on the concentration of just one reactant.

Reaction Rate Constant: This is a proportionality constant in the rate law which varies depending on temperature and catalyst presence but not concentrations.
