Answer» 1. ∆U= q + w w = work done q = heat absorbed 2. G = H- TS or ∆G= ∆H – T∆S 3. In the case of spontaneous process ∆G = -ve

First Law of thermodynamics is the law of conservation of energy. 1. Give the mathematical form of the first law. 2. Write the Gibb’s equation. 3. What is the sign for ∆G for a spontaneous process?

Answer»

1. ∆U= q + w w = work done

q = heat absorbed

2. G = H- TS or ∆G= ∆H – T∆S

3. In the case of spontaneous process

∆G = -ve
