By the way, having gotten interested, I also solved this by brute force trial and error. I assumed an exponential type solution: y = Ae^x + Bxe^x+ C then dy/dx = Ae^x + Bxe^x + Be^x plug that in Ae^x + Bxe^x + Be^x - Ae^x/x - Be^x - C/x = 1/x + 1 + Ae^x + Bxe^x+ C combine like...

**Math Calculus Help**

we know that p = ae^kt using the known values, √e/2 = ae^k e/2 = ae^2k divide to get (e/2) / (√e/2) = e^k √e = e^k so, k = 1/2 now, we see that √e/2 = ae^(1/2) so a = 1/2 p(t) = 1/2 e^(t/2) p(4) = 1/2 e^2

so... k=Ae^(Ea/RT) Do I set it up as ratios? I.e. 0.0000100s-1=Ae^(-Ea/R * 636) ____________________________ 0.000479s-1=Ae^(-Ea/R * 700) A cancels out ...and then solve from there?
