Self-Test 15.4B

Postby Katherine Jordak 1H » Wed Mar 07, 2018 11:09 pm

Hi. When I was doing 15.4B on page 263 of my textbook, one if the reactants' order is not an integer. What would the units of k be in that case?

If the value is not an integer then the units of k are proportional to the fraction. For example, if the reaction order is 3/2 then, the units of k would be L^1/2 * mol^(-1/2) * s^-1.

The overall intention is to end up with the rate in (mol * L^-1 * s^-1), so you would modify the units of k to get that, based on the units of the reactants.
