Respuesta :
a reaction that requires FREE energy it must be non spontaneous so option b is correct.
Answer: The correct answer is Option B.
Explanation:
Gibbs' free energy is defined as the thermodynamic quantity which is equal to the enthalpy of a system minus the product of entropy and the absolute temperature. It is represented by the symbol 'G'
Mathematically,
G = H - TS
where,
G = Gibbs' free energy of the system
H = enthalpy of the system
T = absolute temperature
S = entropy of the system
Sign convention for Gibbs' free energy:
If the value of G is '+ve', it means that energy is required by the system and reaction is considered as non-spontaneous reaction. If the value of G is '-ve', it means that energy is released from the system and the reaction is considered as a spontaneous reaction.
Hence, the correct answer is Option B.
