When molecules having significantly different sizes and interactions are mixed together, it will generate heat of mixing and the local composition will be different from global composition. All these will happen because it is not a mixing of ideal entities.
In case of ideal mixing, heat of mixing becomes Zero, Exces Gibbs free energy becomes Zero.
So Option (a) and (b) are true. So the correct answer is (a) ,(b).

A living cell extracts energy from organic "fuel" molecules in small, enzyme-catalyzed steps. This allows the process of energy extraction to be regulated. but less free energy is released from the molecules than would be released by burning them O and all of the energy is released as heat that can be used to do work in the cell O and some of the energy is stored in bonds of activated carriers O and more free energy is released from...
