HW Problem 9.5

Postby Samantha Jimenez 4k » Fri Feb 15, 2019 5:21 pm

9.5 What is the total entropy change of a process in which 40.0 kJ of energy is transferred as heat from a large reservoir at 800. K to one at 200. K?

For this question, would we just be finding the change in entropies for each and then adding them together?

Yes, calculate it for the 800 and 200 K system and surroundings using S = q/T and add them together.

A lot of these problems involve adding up the steps similar to how you do a Hess's Law problem.

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
