### Different versions of van't Hoff

Is there an advantage to using either form of the van't Hoff equation? I know there's the version in the textbook and the version that Lavelle recommended in class, but are there certain times when it's better to use one form or the other? Thanks!

The advantage to using Lavelle’s is that you can calculate k at different temperatures if delta h is known

Hi,

I think we would determine which equation to use based on the information we are given and what we are trying to solve for.
