WebFeb 12, 2024 · For a zeroth-order reaction, a plot of the concentration of any reactant versus time is a straight line with a slope of − k. For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of − k. WebThe integrated rate law for the first-order reaction A → products is ln [A]_t = -kt + ln [A]_0. Because this equation has the form y = mx + b, a plot of the natural log of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k. Created by Jay. Sort by:

WebThe order of the reaction or enough information to determine it. The rate constant, k, for the reaction or enough information to determine it. In some cases, we need to know the initial concentration, [A o] Substitute this information into the equation for the half life of a reaction with this order and solve for t ½. 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. WebA zero-order reaction thus exhibits a constant reaction rate, regardless of the concentration of its reactant(s).
