WebFor a first order reaction: ln ( [A]) = -kt + ln ( [A]0), the y variable is now ln ( [A]) and the x variable is still time. If we tried plotting ln ( [A]) versus time and get a straight line now, … WebFirst order reaction kinetics is defined as one type of chemical reaction in which the rate of the reaction is dependent only first power of a single reactant. Rate law of a first order reaction is written as -d [A]/dt. [A] is the concentration of reactant A, t is time and -d [A]/dt is the rate of concentration with respect to tome.
WebNope, we are assuming it is a first order reaction because this reaction only has one step. And this step only has one reactant with a coefficient of 1. If this reaction has multiple steps, even if it has one reactant, the order of reaction may not necessarily be equal to 1.
