Zero order reaction

Postby marcus lin 1E » Sun Mar 17, 2019 9:14 am

How do we determine if a reactant is zero order?

It is zero order if its concentration has no effect on the rate.

For instance, a liquid or solid would not affect the rate

You can tell if the concentration doesn’t affect the rate at all. Also the k will be a negative slope.

The graph of a zero order reaction will be [A] vs. time and will have a slope of -K

It will not affect the rate of reaction.

You can derive the integrated rate law from -d[A]/dt= k bc and see that the rate is independent of concentration.

You can determine experimentally, when observing that the initial rates don't change when changing the concentration of the reactants, or by looking at your K units as your K would have to be in the units of M/s to offset the unitless reactant.
