Units of Rate Constant

Is it safe to assume, when finding rate constants, that we should convert all time units to seconds?

It depends upon the context of the question and what's given. If you can solve it with the time units as minutes, then you don't necessarily have to convert it to seconds. What is important is that all units are the same on both sides of the equation and that they cancel.

Not necessarily. As long as the units can cancel out, you can do seconds, minutes, hours, etc.

I would match the units with whatever is given in the problem. This is what the solutions manual seems to do as well.

I don't think so, as long as you convert to what is being asked and consistency throughout the problem.

I wouldn't always convert the time units to seconds, because often times the units depend on the context of the problem. If the problem operates in hours or minutes, then you should use those units.
