Question
A 1st order process with respect to [A] is graphed and found to
have a linear slope of -0.474 min . What is the half-life of the
reaction (in minutes).
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 2 decimal places (regardless of the
significant figures)
Correctly round your answer to the 2nd decimal place (margin
of allowed error is only ±0.01, 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: 12.34 or-0.56
