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

As a good rule of thumb always convert time into seconds.

Always use the standard unit if not specified by the problem.

Also be sure to keep units consistent throughout.

Generally, time is in seconds, so it would be easier to convert all units to seconds.

i think it is safest to use seconds, even if the problem doesn't specify

You should use seconds since the reaction rate is usually in moles/L*s and the reaction constants are derived using those units in mind (e.g. 1st order rate constant units are in 1/s since 1/s multiplied by concentration to the first power (moles/L) equals moles/L*s)

Make sure units are consistent in all your calculations. Generally, time should be reported in seconds.

It is usually best to use the standard units if nothing is specified.

I believe it is good practice to change to seconds but depends on context.

Unless the question states otherwise, it's seconds.

It is almost always seconds, but the problem typically specifies. It's usually best to write units with each step though, so that way it can easily be converted to another unit if necessary.
