### Temperature effect on Entropy

Using the equation

, entropy would decrease as temperature increases. Why is this? Wouldn't you expect entropy to increase as temperature increases because the molecules are in a more disorderly state as temperature increases?

This confused me too, but the thing to remember is that the equation is solving for the change in entropy, not entropy itself, and the temperature in the equation is a constant, not change in temperature. If a system is already at high temperature and the molecules are excited, it's change is entropy will not be as dramatic as it would be if it were at a lower temperature. Hope this helps!
