You discover the enthalpy by taking the aggregate of the inward energy of the framework in addition to the result of the weight of the gas in the framework and its volume
you locate the free energy by taking the adjustment in enthalpy short the temperature (in Kelvin) * change in entropy.
positive enthalpy change and negative entropy change is NEVER spontaneous, in light of the fact that with a specific end goal to have a spontaneous response, the free energy must be NEGATIVE. a positive number short a negative number will dependably give you a positive number (see above portrayal of how to discover free energy)
Dissolving gold bars will build the entropy since you transform it from strong state to fluid. Changing from strong to fluid will build the space between particles, so it will expand the possibility of scatters to scatter energy.
