Rate Unit Conversion

Postby Silvino Jimenez 1A » Tue Mar 06, 2018 1:49 am

Is it necessary to convert the units of a rate to metric units of time, seconds, when doing rate calculations in (mols/Ls)?

The rate has to have units that match with the rate constant, k. k usually has s^-1 in its units, but there is a chance that a problem will give a constant with minutes or something.

Usually conversions will simply involve changing minutes into seconds or hours into seconds.

I remember that on the test we took on kinetics, when asking for half time, the question specifically asked for the answer to be in seconds. So, probably, the best would be to use seconds unless the problem specifically asks for another measurement of time to be used.

It will vary from question to question. sometimes the question will specify which units it wants it in. sometimes you can just leave it in the units they give you to begin with.
