At 298 K, this reaction to produce phosphoryl chloride has a standard enthalpy of A,H° = -620.2 kJ mol-¹. 2 PC3(g) + O2(g) → 2 POCI3(1) The standard molar entropies, in J K-1 mol-1, for these species are: PC13(g) [308.5]; O2(g) [205.1]; POCI3(1) [215]. What is the standard Gibbs energy of reaction at 298 K? (Note: Some of these numbers have been changed from their actual values for the purpose of the exam.) (Determine answer in units of kJ/mol with one decimal place. However, do not enter units with your answer.)
