Explanation:
The integrated rate law for first order kinetics is given by;
[A] = [Ao] ^-kt
Where;
[A] = concentration of cyclopropane at time = t
[Ao] = initial concentration of cyclopropane
k = rate constant
t = time taken
From the question, we are told that 99% of cyclopropane disappeared hence;
[A] = 0.290 - (0.99 * 0.290)
[A] = 0.290 - 0.2871
[A] = 0.0029 M
Hence
0.0029 = 0.290 e^-2.74 x 10^ - 3 * t
0.0029/0.290 = e^-2.74 x 10^ - 3 * t
0.01 = e^-2.74 x 10^ - 3 * t
ln(0.01) = -2.74 x 10^ - 3 * t
-4.61 = -2.74 x 10^ - 3 * t
t= -4.61/-2.74 x 10^ - 3
t = 1866.4 secs
