A. 17 kJ
B. 1300 kJ
C. 0.63 kJ
D. 75kJ

Respuesta :

The Gibbs Free Energy at 298 K, AH = 46 kJ/mol and sº = 0.097 kJ/(K-mol) is 28.906 kJ/mol

What is Gibb's Free Energy ?

It serves as the single master variable that determines whether a given chemical change is thermodynamically possible.

Thus if the free energy of the reactants is greater than that of the products, the entropy of the world will increase when the reaction takes place as written, and so the reaction will tend to take place spontaneously.

Conversely, if the free energy of the products exceeds that of the reactants, then the reaction will not take place in the direction written, but it will tend to proceed in the reverse direction.

At 298 K,

AH = 46 kJ/mol

and sº = 0.097 kJ/(K-mol).

ΔG=ΔH−T⋅ΔS

ΔG = 46 - 298 * 0.097

ΔG = 46 - 28.906

ΔG = 28.906 kJ/mol

The Gibbs Free Energy at 298 K, AH = 46 kJ/mol and sº = 0.097 kJ/(K-mol) is 28.906 kJ/mol
