Grade 12 Thermodynamics

Given that ΔG = Gibb's free energy change
ΔH = Change in enthalpy of the system
ΔS = Change in entropy of the system

Which of the following expressions correctly describes Gibb's free energy change for a chemical reaction that is carried out at constant temperature?
  1. ΔG=ΔH-TΔS
  2. ΔG=ΔH+TΔS
  3. ΔG=ΔHTΔS
  4. ΔG=ΔH×TΔS
