What is AG° (in kJ/mol) for the autoionization of water at 25°C? R = 8.314462 J/K-mol IMPORTANT: When entering your answer: • Enter the number only (no units) • Do not leave any spaces • Include the sign if your answer is negative (not necessary for positive values) • Use a leading zero before the decimal when necessary Report your number to 1 decimal place (regardless of the significant figures) • Correctly round your answer to the 1st decimal place (margin of allowed error is only ± 0.1, so always use un-rounded numbers in your calculations). If the last digits are zeros they will not display once you click away, but the answer will still be marked correct. Examples: 12.3 or -0.4
