I am not sure how they calculated the ln 5. I would like to possibly see a more detailed step for this solution.

Step 1

The initial concentration, which 100% of C4H8 is not known. Let it be x.

About 80% of C4H8 is decomposed.

The final concentration of C4H8 at time t is 100% of x- 80% of x = 20% of x

That is 20/100(x) = 0.2x present at time t.
