Why does iodine, $\mathrm { I } _ { 2 }$ (s),spontaneously sublime at room temperature?
A)The contact of iodine, $\mathrm { I } _ { 2 }$ (s),with the water vapor in the air causes the sublimation process.
B)Iodine, $\mathrm { I } _ { 2 }$ (s),pulls $\mathrm { O } _ { 2 }$ from the air as it self-oxidizes under sublimation to $\mathrm { I } _ { 2 }$ (g).
C)There is an increase in entropy as solid iodine, $\mathrm { I } _ { 2 }$ (s),sublimes into iodine vapor, $\mathrm { I } _ { 2 }$ (g),because in the gaseous phase energy is more readily dispersed.
D)The reaction of $\mathrm { I } _ { 2 }$ (s)subliming to $\mathrm { I } _ { 2 }$

The sublimation of iodine from solid to gas involves an increase in entropy, as the gaseous phase allows for greater dispersion of energy compared to the solid phase. This is a key factor in the spontaneous sublimation of iodine at room temperature.
