The correct answer of gibbs free energy is -232 KJ.
ΔG = -nFE° = -2*96485*1.20 = -232 (kJ)
The Gibbs free energy of a system at any point in time is defined as its enthalpy minus the product of its temperature times its entropy. Because it is defined in terms of thermodynamic properties that are state functions, the system's Gibbs free energy is a state function. It is commonly referred to as free energy because it is readily available at all times. If necessary, the reaction can steal this energy without having to pay or work for it. The reaction between sodium chloride and water is regarded as spontaneous, and it has a negative G. When solid NaCl is immersed in water, it begins to dissociate on its own without any external assistance.

The sample has a new pressure of 274kPa. If at 105 kPa and 275K, a 220 mL sample of helium gas is contained in a cylinder with a moving piston. The sample is pushed till it has a 95.0 mL volume and 310K .
The macroscopic characteristics of ideal gases are related by the ideal gas law (PV = nRT). A gas is considered to be perfect if its particles (a) do not interact with one another and (b) occupy no space (have no volume). Where P= pressure V= volume and T = temperature.
From ideal gas equation
P₁V₁/T₁ =P₂V₂/T₂
105×220÷275 = P₂ ×95÷310
P₂= (105×220×310)÷(275×95)
P2= 7161000/26125
P2 = 274.105 kPa
Hence, the new pressure of helium gas is 274kPa
