### Equation

During lecture, Dr. Lavelle mentioned that Van't Hoff used a different equation than the one we are more likely going to use. Why exactly did he use a different equation and what for?

### Re: Equation

I believe he said it is more commonly used in the form that he stated, and that it is more applicable.

### Re: Equation

The reason is that the equation we usually use is a version derived from what the Vant Hoff equation originally was; the actual scientist discovered an equation that was expanded on a bit further for most formula sheets.

### Re: Equation

He just wanted to make sure that we knew that the equation we most commonly use is not the actual Van't Hoff equation but a version of it more applicable to questions that we would be asked.

### Re: Equation

We are not technically using the Van't Hoff Equation, we are using a derivation that is useful for the purposes of this class.
