$\frac{d[R]}{dt}=-k[R]^{2}; \frac{1}{[R]}=kt + \frac{1}{[R]_{0}}; t_{\frac{1}{2}}=\frac{1}{k[R]_{0}}$

2C4H6(g) → C8H12(g)
The dimerization reaction of butadiene is second order and has a rate constant of 0.0140M-1·s-1 at 500˚C. Determine the C4H6 concentration
after 115.0 seconds if the initial concentration of C4H6 is 0.0500 M.

I tried solving this part of the problem, but my solution doesn't quite match the one Dr. Lavelle has on page 10 of his PDF. Did anyone else face this problem?

Good catch!

The answer should be: [A] = 0.0463 M

I corrected my file, converted to PDF, logged onto server, and posted updated file.
