Question : For a spontaneous process
Option 1: ΔG is +ve
Option 2: ΔG is -ve
Option 3: ΔG is equal to zero
Option 4: ΔH is -ve
Answer (1)
Correct Answer: ΔG is -ve
Solution : The correct answer is ΔG is -ve.
For a spontaneous process, the change in Gibbs free energy (ΔG) is negative. The Gibbs free energy is a thermodynamic potential that combines enthalpy (ΔH) and entropy (ΔS) in a system. It is described by the equation:
ΔG=ΔH−TΔS
- ΔG is the change in Gibbs free energy,
- ΔH is the change in enthalpy,
- T is the temperature in Kelvin, and
- ΔS is the change in entropy.
