When white phosphorous (P4) is heated above 1100 K, the following equilibrium is observed in the gas phase P4 ? 2P2 b. The equilibrium constant has been measured as a function of temperature for this reaction, leading to values of ?S = 107 J/mol K and ?H = 232 kJ/mol. Comment on the signs (both positive) for these quantities. c. There are two possible structures for the species P6. What would they be? (Remember you need to satisfy the bonding requirements of phosphorous)
