WebThe reaction is zero order in CO; thus n = 0. The rate law is: rate = k[NO2]2[CO]0 = k[NO2]2 Remember that a number raised to the zero power is equal to 1, thus [CO] 0 = 1, which is why the CO concentration term may be omitted from the rate law: the rate of reaction is solely dependent on the concentration of NO 2. 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.

If adding the reactant decreases the half-life, the reaction has second-order kinetics. Q2. What exactly is the Zero Order Reaction? 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
