Well, today in my chemistry lab, my teacher let us out early without getting the class to answer a few questions, and now I'm stuck on my lab report! We were supposed to have a class discussion, but we didn't. I was wondering if anyone knew how to answer the following questions: If delta G and delta H for a reaction are both negative what will the sign of delta S be and why? If delta G is negative and delta H is positive for a reactoin, what will the sign of delta S be and why? I do know that delta G = delta H - T delta S, but that's about it. Any help is greatly appreciated. Thanks!
