The rearrangement of cyclopropane to propene at 500 °C (CH2)3 CH3CH=CH2 is first order in (CH2)3...

The rearrangement of cyclopropane to propene at 500 °C (CH2)3 CH3CH=CH2 is first order in (CH2)3 with a rate constant of 6.70×10-4 s-1. If the initial concentration of (CH2)3 is 6.15×10-2 M, the concentration of (CH2)3 will be M after 1889 s have passed.

This is what i have so far but i do not know how to cancel the ln. Teacher in class said "take e^x of both sides to cancel but did not explain this at all.

ln ((7.36x10^-2 M)/[PH3]t) = (1.8 x 10^-2 s -1)(113 s)

ln((7.36x10^-2 M)/[PH3]t) = 2.034
