When can we assume that delta entropy would be the same for different temperatures. Do the temperatures have to be close together?

We always assume that delta S is the same at different temperatures because we can assume that the difference in delta S between the reactants and products is the same at two different temperatures.

You have multiple equations for finding the change in entropy. One is . You use this equation when the temperature is constant. The other equation is . This equation is used when you have a final temperature that is different from the initial temperature.

Temperature affects entropy because at higher temperature, there are more possible states for particles increasing entropy and vice versa for lower temperatures.
