So the rate constant, k, is ( l n 2) / t 1 / 2, which is about 0.053 s − 1. Hence the initial slope is -k times 0.4 M, giving 0.021 M s − 1 as the magnitude of the initial slope. Rounded to one significant figure, this is 0.02 M s − 1, as per answer A.

The given integrated rate law of a zero-order reaction is: [A]t = -kt + [A]0. At half-life the concentration is half of its original amount, so [A]t = [A]0/2. [A]0/2 = -kt + [A]0, after the substitution.
WebFeb 1, 2024 · For any First order reaction, the rate is expressed as: Rate = k [A] Where k is rate constant ⇒ mol L-1 sec-1 = k (mol L-1) ⇒ k = sec-1 Thus the rate constant units (k) for the First-order reaction is sec-1 …
WebFeb 12, 2024 · To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus time and see whether the graph is linear. If the graph is linear and has a negative slope, the reaction must be a first-order reaction. shun lee nyc menuthe outlaws willie nelsonWebNov 25, 2024 · The graph of Rate of reaction against time: The differential rate law for the first order reaction is It is of the form y = mx + c.
