Question

Define and explain Free energy

Answer 1

Gibbs free energy specifically refers to the energy associated with a chemical reaction that is available after accounting for entropy. In other words, Gibbs free energy is usable energy or energy that is available to do work.

Answer 2

$\bold{free \: energy}$

It is the maximum amount of energy available to a system during a process to be converted into useful work.

$\bold{g \: = \: h \: - ts}$

If there is decrease in free energy during a process or reaction then the process then the process or reaction is spontaneous.

It is state function like

$\bold{internal \: energy \: and \: enthalpy}$

.When the pressure and temperature are constant it is known as

$\bold{gibbs \: free \: energy}$

$\: it \: is \: a \: type \: of \: \bold{state \: function} \\ \: that \: balance \: the \: influence \: of \\ \bold{energy \: and \: entropy}$
