Find K from AG Substance ΔΗ, kJ/mol AG kJ/mol s /(mol-K) OH' (aq) -230.0 -157.244 -10.9 H20*(aq) 285.83 -237.1 69.95 H2O(g) -241.8 228.6 188.8 H2O(0) 285.8 -237.1 70.0 What is the AG*rxn for the autoionization of water? What is the change in free energy (in kJ) when 100.0 mL of 2.00 M NOOH (aq) and 100.0 mL of 2.00 M HCI (ag) are mixed? We can assume that Na* (aq) and Ct(09) remain unchanged throughout the reaction. (Review: dimensional analysis) Calculate the K value at 298K using the AG What is the AG when the molarity of OH and H,09 ore 0.500 M at the time of reaction? Using the AH and S* data, calculate AG* of the autoionization of water at 50°C. How does it compare to AG at 25°C (298K)? What accounts for this change?
