What is the relationship between ∆G, ∆H, and ∆S in the free energy change equation?
What is the relationship between ∆G, ∆H, and ∆S in the free energy change equation?
- ∆G = ∆H * T∆S
- ∆G = ∆H + T∆S
- ∆G = ∆H / T∆S
- ∆G = ∆H - T∆S (correct)
What is the role of activation energy (Ea) in chemical reactions?
What is the role of activation energy (Ea) in chemical reactions?
- It is the total energy released in a reaction.
- It is the energy required to initiate a reaction. (correct)
- It is the same as free energy change (∆G).
- It provides energy at the end of a reaction.
