If the following reaction 2 C4H10 (g) + 13 O₂ (g) →8 CO₂ (g) + 10 H₂O(g) has AH = -115 kJ/mol and AS°= +248 J/K mol, how would the reaction be characterized with regards to its spontaneity? Periodic Table e Potentially Useful Information: AS n = (n*AS)products - (n*AS)reactants AG-AH-TAS AGxn- (n'AG)produts - (n'AG)reactants AG-AG + RT InQ K= e(Gorn/RT O spontaneous at all temperatures O spontaneous only at high temperature O spontaneous only at low temperature O nonspontaneous at all temperatures O unable to determine without more information Given the following table of thermodynamic data, AH, (kJ/mol) Substance H₂O2(g) H₂O2(0) for the following reaction being conducted at 298K H₂O2(1)→ H₂O2(g) 1. Calculate the AGºrxn -136.30 -187.80 answer yes or no AS (J/mol K) 232.60 110.00 kJ Report value to 4 sig figs 2. Is the reaction spontaneous under these standard state conditions?
