5.In a simple reaction A ↔ A*, a molecule is interconvertible between two forms that differ in standard free energy ...

ard free energy G° by 18 kJ/mole, with A* having the higher G°. Use the table below to find how many more molecules will be in state A* compared with state A at equilibrium. If an enzyme lowered the activation energy of the reaction by 11.7 kJ/mole, how would the ratio of A to A* change? Table: RELATIONSHIP BETWEEN THE STANDARD FREE- ENERGY CHANGE, ∆G°, AND THE EQUILIBRIUM CONSTANT Hint: ∆G° represents the free-energy difference under standard conditions (where all components are present at a concentration of 1 mole/litter). From this table, we see that if there is a favourable free-energy change of –17.8 kJ/mole for the transition Y→ X, there will be 1000 times more molecules of X than of Y at equilibrium (K = 1000).

7.Hi I am studying in my free time about redox/reduction reactions and electrolysis. Can you please help me understand how these ...

help me understand how these two work. I think they both worth by donating hydrogen ions. If a reduction reagent can be used in a reaction, can electrolysis always be substituted in its place because it works by the same mechanism? Also, what is the difference in properties of different reduction reagents. For example magnesium vs zinc, they are both electropositive elemental metals. So will they always react the same but just at different rates?
