What is the overall order and the units for the rate constant K for the following chemical reaction shown below that has a rate equal to K NL2 to the two, CL2 to the one. All right, so remember two and one are your reaction orders. To find your overall order you just add them together. So this would be 2 + 1. So your reaction would be third order overall.
Now for K we'd say. Remember K is M to the negative N + 1 times time. Inverse here. Time could be in units of seconds, minutes, gears, whatever. So this would be M to the -3 + 1. Here. Let's just say seconds are the units of time that we're looking at, and so this would be M to the -2 times seconds inverse.
So whatever the actual value of K would be, these would be the units that follow it. So it would be some value M to the -2 * s to the -1. So we'd be third order overall and these would be the units for our rate constant K.
