5. A student is asked to find the rate constant for a first-order reaction, given that (Alo = 10 M and after 20 s the concentration of A is 2.5 M. The student uses the following logic:2 rate = k[A] (for a first-order reaction) So: A[A] – k[A] Δt' Inserting the values gives: (2.5 M - 10 M - 205-05") = k[2.5 M] Solving for k gives 0.15 5-1. a. Do you agree with the student's answer? Why or why...
