Van’t Hoff Equation

[805383532]

What does the equation measure? How does it relate to gibbs free energy?

[Aliya Jain 2B]

The Van't Hoff Equation can be used to calculate the k at a different temperature if change in enthalpy is known and is constant.

The vant hoff equation can be used to calculate K at different temperatures if stand enthalpy of real lion is known.

The vant hoff equation can be used to calculate K at different temperatures if stand enthalpy of real lion is known.

what is real lion

[Maya Pakulski 1D]

The vant hoff equation can be used to calculate K at different temperatures if stand enthalpy of real lion is known.

what is real lion

probably "real ion" if I had to guess

[Veronica_Lubera_2A]

Van't Hoff's equation is:

ln(K2/K1)= (-DeltaH/R)(1/T2 - 1/T1)

So the equation relates enthalpy too but this value should be given in the problem.

[Mai V 4L]

Will this be on the final exam formula sheet?

[AKatukota]

Should we also know to derive it?

[JohannaPerezH2F]

it is used to calculate k at different temperatures

[Julia Holsinger_1A]

How do you know to use Van't Hoff Equation? Are there certain questions in problems that signal to use it?

[Callum Guo 1H]

ln(K2/K1)= (-DeltaH/R)(1/T2 - 1/T1)


you can use it to calculate K value at a temperature given the K value at another temperature

[Jacob Motawakel]

You can calculate K at different temperatures with the Van't Hoff equation. I don't see how it relates to DeltaG though because the only relation between DeltaG and K is with standard DeltaG, and since Van't Hoff equation doesn't calculate K at standard conditions, you can't use that K in the equation: standard DeltaG = -RTlnK
