Units of T

Postby Antonio Melgoza 2K » Wed Feb 17, 2016 5:45 pm

Does it matter if time is in min/sec/hr if the question doesn't specifically state what it wants?

If the question doesn't specifically state I would recommend answering in the units given or if not answering in seconds since it is the standard unit for time.

Since you will be plugging in time in integrated rate laws that use the natural log, when you solve for T the units will cancel and time should just be in the units that you've plugged it in for. For example, for a 1st order reaction half life the equation is .693/k, and the time units don't get canceled out.
