Quick overview of our lesson: Our topic is all about Second Law of Thermodynamics. Gibbs’ free energy, G is defined by G = H – TSwhere H is the enthalpy, T is the temperature (in Kelvins), and S is the entropy. In a chemical reaction,R ↔P (R are reactants and P are products) at aconstant temperature we have ∆G = ∆H – T∆S.If ∆G < 0 the reaction may proceed spontaneously tothe right.If ∆G = 0 the reaction is in equilibrium.If ∆G > 0 the reaction may proceed spontaneously to the left. do me with the questions on the picture Transcribed Image Text: 2. Observe the Figure 2.0, in which there are 4 types of reactions. Using the definition of
Gibbs’ free energy. Identify which is a spontaneous reaction and explain why on the space
provided.
