Question

Choose the correct option that represents the change in gibbs free energy ​

Answer 1

Answer:

Gibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, ΔG, is equal to the sum of the enthalpy plus the product of the temperature and entropy of the system.

Answer 2

Gibbs free energy:

• Gibbs free energy, abbreviated as G, is a single value that combines enthalpy and entropy.

• The sum of the enthalpy plus the product of the system's temperature and entropy is equal to the change in free energy, G.

• Under two conditions, G can forecast the direction of a chemical reaction:

• Temperature and pressure are maintained at the same levels at all times.

• If G is positive, the reaction is nonspontaneous (i.e., it requires the input of external energy to occur), while if G is negative, the reaction is spontaneous.
