WebFor 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. Additionally the slope, m, will be -k and the y-intercept, b, will be the initial concentration of the reactant. WebBasic rate constants are measured in k. ‘k’ depending on the overall orders of the reactions. In a zero-order reaction, the unit of k is M/s. In a first-order reaction, the unit of k is 1/s. In a second-order reaction, the unit of k is 1/(M-s). Determination of Reaction Order
