Why Does Iodine, I₂ (S), Spontaneously Sublime at Room Temperature

question 37

Multiple Choice

Why does iodine, I₂ (s) , spontaneously sublime at room temperature?

• A)The contact of iodine, I₂ (s), with the water vapor in the air causes the sublimation process.
• B)Iodine, I₂ (s), pulls O₂ from the air as it self-oxidizes under sublimation to I₂ (g).
• C)There is an increase in entropy as solid iodine, I₂ (s), sublimes into iodine vapor, I₂ (g), because in the gaseous phase energy is more readily dispersed.
• D)The reaction of I₂ (s)subliming to I₂ (g)is highly exothermic and therefore proceeds spontaneously.
