delta s

[Ghadir Seder 1G]

Why do we assume delta s naught is constant in the van't hoff equation?

[Jonathan Gong 2H]

delta S naught is the entropy of the reaction at standard conditions. Since standard conditions are defined, delta S naught will be a constant/always have the same value.

[Bryce Barbee]

This is because delta S naught is the standard entropy of that reaction, therefore making it constant. We then have to include the temperature to show how the observed entropy can change depending on how you change the different parameters such as temp.

[William Francis 2E]

ΔS° is defined as entropy change in a set of standard conditions. ΔS° won't change for a given reaction unless those standard conditions do.

[VPatankar_2L]

Delta S is constant in the Vant Hoff equation because the change in entropy of the system at equilibrium is constant. Delta S doesn't increase because it has reached its maximum.

[Jacob Villar 2C]

Delta S won’t change under standard conditions.

[Noe BM 1J]

It won't change unless standard conditions are changed

[sarahartzell1A]

Because delta s won't change in those conditions!

[rabiasumar2E]

Because standard conditions don't change !

[rohun2H]

Delta s does not change, both s values may change but the difference between final and intitial remains constant.
