Sample Problem 16.4
PLAN:
SOLUTION:
Determining reaction concentration at a given time
(a) If the initial [C4H8] is 2.00 M, what is the concentration after 0.010 s of reaction?
(b) What fraction of C4H8 has decomposed in this time?
Find [C4H8] at time t using the integrated rate law for a 1st-order reaction. Once that value is found, divide the amount decomposed by the initial concentration.
= 0.58
= 0.87
2.00 M / [C4H8]t = e0.87 = 2.4
[C4H8]t = 0.83 M
