Yeah the section introduces that equation but I have no idea how to get from that to the equation I posted. Any thoughts?

thanks!

Yeah, answer the question HallsofIvy asked you.

(I also wondered that)

Also please tell us if you have done any dimensional analysis and if so have you tried it on the equation you posted?

Dimensional analysis can quickly and easily identify if an expression is possibly correct or definitely incorrect and can even help deduce new equations/relationships/formulae.

I can tell you that your equation is dimensionally consistent.

I would guess that your equation derives from equating the gain (could be negative) of kinetic energy of the particle to the change in potential energy of the particle, from time t1 to t2 (hence delta t). Calculating the change in potential energy would involve integrating V(x) along the path ie the x axis.

I think that Physical Chemistry is a fascinating subject, but it does require a higher level of maths than 'wet' Chemistry.

A really good and clear book to have for this (study and reference and reference) is

Erich Steiner

The Chemistry Maths Book

Oxford University Press

Here is a clear and simple introduction to Dimensions and a useful table of them in PDF format.
