Van't Hoff

Postby Jared Smith 1E » Wed Feb 14, 2018 4:51 pm

Can someone give me a situation where you would use the ln(k2/k1) version of this equation? Thanks!

As I stated in class when calculating K2 at T2 when you know K1 at T1.

From the notes that I took, you can use Van't Hoff when you have two different temperatures and you are trying to calculate the K, accounting for the face that you need to subtract temperatures to find the deltaT.

Would the above situations be the only ones where this equation is used?

Is this equation only used when K1 at T1 is known?

Do we have to know the van't Hoff equation for the final?

I think you should be able to derive the Van't Hoff equation with what's given on the equations sheet.

I actually learned to calculate this and turned out it wasn’t on the final. But it’s good to know the concepts.

I think that this equation can be used for different temperatures and also different Ea as well.

Yeah I agree with the statement above.
