Problem: The half-life of N2O5 (g) at a 25 °C is 4.03 x 104 s. The rate constant is 1.72 x 10-5 s-1b) Determine the fraction of N2O5 molecules that remain unreacted after 24h.

FREE Expert Solution

We are asked to determine the fraction of N2Omolecules that remain unreacted after 24h


The integrated rate law for a first-order reaction is as follows:


ln[A]t = -kt + ln[A]o


where:

[A]t = concentration at time t 

k = rate constant

t = time, [A]0 = initial concentration
