Question

Is free energy released or absorbed, generally, when a nonpolar molecule is transferred from water to a nonpolar solvent?

Answer 1

Step-by-step explanation:

Non-polar molecules are the molecules which readily dissolve in non-polar solvents.

And, a spontaneous process is defined as the process that will occur on its own without any input of energy from its surroundings.

Therefore, a spontaneous process will always lead to increase in entropy and for a process to be spontaneous at every temperature will have a negative change in enthalpy, that is,
`\Delta H`.

As,
`\Delta G = \Delta H - T \Delta S`

= (-ve) - (-ve)

= -ve

Therefore, we can conclude that free energy will be released when a non-polar molecule is transferred from water to a non-polar solvent.
