chemistry assignment and need help with thermodynamics problems. Specifically, I’m stuck on calculating Gibbs free energy using ?G = ?H - T?S. I understand the formula, but the units always trip me up. For instance,help with chemistry assignment, ?H is given in kJ, and ?S is in J/K, so I end up with the wrong ?G value.
How do I make sure I’m consistent with units? Also, can anyone explain when ?G is negative, zero, or positive in a reaction? I’m confused about how it relates to spontaneity and equilibrium.
Thermodynamics has so many overlapping concepts, like enthalpy, entropy, and Gibbs energy, and it’s hard to keep them all straight. If anyone has a clear method for organizing these ideas or knows of any practice resources, please let me know.
I want to improve my understanding because this assignment help online coming up in my coursework. Any tips, tricks, or study guides would be amazing. Thanks in advance for your help!
