The breaking of the O-O bond in peroxydisulfuryl difluoride (FO,SOOSO,F) gives FO,SO: (FO2SO)2 2 2 FO2SO The compound on the left of this equation is a colorless liquid that boils at 67.1°C. Its vapor, when heated to about 100°C, turns brown as the product of the reaction forms. Suppose that, in a sample of the vapor, the intensity of the brown color doubles between 100°C and 110°C and that the total pressure increases only by the 2.7% predicted for an ideal gas. Estimate AH° for the preceding reaction.

Question
The breaking of the O-O bond in peroxydisulfuryl
difluoride (FO,SOOSO,F) gives FO,SO:
(FO2SO)2 2 2 FO2SO
The compound on the left of this equation is a colorless
liquid that boils at 67.1°C. Its vapor, when heated to
about 100°C, turns brown as the product of the reaction
forms. Suppose that, in a sample of the vapor, the intensity
of the brown color doubles between 100°C and 110°C
and that the total pressure increases only by the 2.7%
predicted for an ideal gas. Estimate AH° for the preceding
reaction.
