Chapter 18, Problem 69E

Interpretation Introduction

Interpretation: For the following reaction depicting the sublimation of iodine:

$I_2\left(s\right)\to I_2(g)$

$\Delta G_{\text{rxn}}^{\text{o}}$ for the above reaction is to be determined

$\Delta G_{\text{rxn}}^{}$ at 25.0 °C under the following nonstandard conditions are to be calculated:

P_I2 = 1.00 mmHg

P _I2 = 0.100 mmHg

The reason why iodine spontaneously sublimes in open air at 25.0 °C is to be explained.
