Understanding Gibbs Free Energy change. Identifying reactions that are thermodynamically spontaneous.
The attached problem file shows the standard Gibbs Free Energy Change for two reactions. Considering these values, which reaction is more favoured or spontaneous?
A reaction with a delta Go = 16 kcal mole-1?
Or a reaction with a delta Go = -16 kcal mole-1?
...on is an uphill battle, and energy must be expended in order to make the reaction "go".
On the other hand, if the energy level of the reactants is greater than the energy level of the products, then the reaction is an easy coast downhill, and energy will be released as the reaction proceeds.
The Gibbs Free Energy change (DG) indicates the total amount of energy change that ...
