Answer:
ΔG for the given system is 28.421 kJ. The system is non spontaneous.
Explanation:
ΔH = 147 kJ =147,000 J= Enthalpy of the system
ΔS = -67.0 J/K = Entropy change
T = 149 °C = 422.15 K = Temperature of the system
((T)°C=273.15 +T K)
ΔG = Gibbs free energy ?
The Gibbs free energy 's expression is given by:
ΔG = ΔH - T ΔS
- ΔG > 0 , non spontaneous
- ΔG < 0, spontaneous

ΔG = 28,421 J = 28.421 kJ
Since, value of Gibbs free energy is positive this means that reaction is non spontaneous.
The best answer is, “Two clear liquids combine and turn cloudy.”
When water freezes form a liquid to a solid. That’s a physical change.
When water boils, it forms bubbles. That’s a physical change.
When you mix ethanol and water, they form a clear solution. That’s a physical change.
Try this solution, all the details are described in the attached picture.
0s to 15s: constant speed/zero acceleration
15s to 40s: constant gradient, therefore constant deceleration
