T1/2 of first order reaction
WebFeb 12, 2024 · Since the reaction order is second, the formula for t1/2 = k-1 [A] o-1. This means that the half life of the reaction is 0.0259 seconds. 3 Convert the time (5 minutes) to seconds. This means the time is 300 seconds. Use the integrated rate law to find the final concentration. The final concentration is .1167 M. References

If the rate constant of the reaction is 3.45 times 10^-3 s^-1, what is the half-life [t, 1/2) of the reaction? (1 A second-order reaction (2A rightarrow B) with a rate constant of 0.350 M^-1 s^-1 is found to have a half-life of 3.45 s. What was the initial concentration of the reactant, [A]_0?
WebFeb 12, 2024 · The pseudo-1 st -order reaction equation can be wr itten as: [A] = [A]oe − [ B] kt or [A] [A]o = e − k t. By taking natural logs on both sides of the pseudo-1st-order equation, we get: ln( [A] [A]o) = k t. Because the concentration of A for a half-life t1 / 2 is 1 / 2[A]o : ln(1 / 2[A]o [A]o) = ln(1 2) = − k t1 / 2.

WebJan 30, 2024 · The 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:
