Was bedeutet ein hoher/ großer Entropiewert?

You mean a big, positive reaction tropy with “great entropy value”?

This means that the entropy (≅”unorder”) increases in the course of the reaction.

This, in turn, has the consequence that the reaction…

a) can always proceed voluntarily if it is exothermic.

b) even if it is endothermic, it can take place voluntarily as long as the temperature is high enough.

Image:

🔼G: voluntarily ⬅️🚘➡️ involuntary

🔼H: exotherm⬅️🚘➡️endotherm

🔼S: pos. Entropy ⬅️🚘➡️ neg. Entropy

When 🔼H and 🔼S show in the same direction, it is clear where the car is going.

When 🔼H and 🔼S show in different directions, the greater influence “wines” and DeltaS becomes more and more influential with increasing temperature.

🔼G = 🔼H – T•🔼S
