$\huge\bf\underline{\red{Y}\green{o}\orange{u} \pink{r}\:\red{a}\purple{n}\blue{s}\orange{w}\red{e} \purple{r}}$

A first-order reaction depends on the concentration of only one reactant. As such, a first-order reaction is sometimes referred to as a unimolecular reaction. While other reactants can be present, each will be zero-order, since the concentrations of these reactants do not affect the rate.
