"WebWe essentially rearrange a reaction order's integrated rate to resemble a linear equation of the form: y=mx+b. For a zeroth order reaction: [A] = -kt + [A]0, the y variable is the reactant concentration or [A], the x variable is time or t. If plotting [A] versus t yields a straight line then the reaction is zeroth order. " - How to solve half reactions
