Gibb's free energy (? G) -

$\Delta G= \Delta H-T \Delta S$

- wherein

$\Delta G=$ Gibb's free energy

$\Delta H=$ enthalpy of reaction

$\Delta S=$ entropy

$T=$ temperature

$2H_{(g)} \rightarrow H_2_{(g)}$

degree of randomness decreases

$\therefore$ entropy decreases and is negative.

Option 1)

Option 3)

Sublimation of solid to gas
