WebA zeroth-order reaction is one whose rate is independent of concentration; its differential rate law is rate = k. We refer to these reactions as zeroth order because we could also write their rate in a form such that the exponent of the reactant in the rate law is 0: Equation 14.15 WebAs shown in Figure 18.4.6, a plot of [A] versus t for a zero-order reaction is a straight line with a slope of −k and a y-intercept of [A] 0. Figure 18.4.6. For a zero-order reaction, a plot of the concentration of the reactant (A) versus time (t) results in a straight line.

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.
