Van't Hoff equation

Postby Gabriella Bates 2L » Sat Feb 22, 2020 10:30 pm

Is the Van't Hoff Equation on the equation sheet, or do we need to derive it? I didn't see it on the sheet but I may just be blind

The learning objectives ask you to be able to derive this equation.

What is this equation used for? When would we know to use it or to derive it?

The equation relates K with temperature and it isn’t on the equation sheet. However, the equations you need to derive it are on the equation sheet.

The Van't Hoff equation relates K with temperature. K1 corresponds with T1 and K2 corresponds to T2.

Should we be able to derive both versions of the equation or would just know the main derivation be enough?

I heard from my TA that you need to know how to derive it for the final. She said points could be given based on deriving it.

I think it is important that you know how to derive this equation

Although this isn't on the equation sheet itself, you should know how to derive it. It basically draws a relationship between temperatures and K values that are changing/ different.

Since the outline says you should be able to derive the equation, I would recommend it. Also, it isn't given on the constants sheet so it is a good thing to know. During a step-up session one of the UA's said that they had to derive the equation on their final.

Although derivations of equations will not be on any tests, it is still important to understand them conceptually. So I would say just know it.
