Question
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
