I'll discuss the Van't Hoff Equation in class tomorrow.

The equation allows us to relate a change in temperature to a change in the K value for a chemical reaction at equilibrium.

The Van't Hoff equation can be used to calculate K at a different temperature if delta H is known.

### Re: What is this?

It is used to calculate K when delta H and S are known.

### Re: What is this?

What are the constants in this equation? (example: constant pressure)

### Re: What is this?

would it be unitless since it is calculating K?

Correct K does not have units.
