Red phosphorous is formed by heating white phosphorous. White phosphorous is the stable form of elemental phosphorous in nature. Given the following data: white phosphorous: S° = 41.1 J/mol-K red phosphorous: AHF° = -17.6 kJ/mol; S° = 22.8 J/mol-K calculate the temperature at which the transformation of white phosphorous to red phosphorous is in equilibrium. You may assume that the values of S° and AHf given above are constant at all temperatures.
