Units

Postby Daniel Yu 1E » Sat Mar 14, 2020 8:19 pm

What are the units for k in a zero order reaction? What are the units for the reactants of a zero order reaction? I don't understand why the units are what they are can someone help me?

The units for k in a zero order reaction is M/s.

Rate is generally described as
The zeroth order is described by and since , the units remain as

I think the units for a zero order reaction are molarity per second (or M/second). In a zero order reaction, the reactant is just pretty much colliding with the walls of the space it is within, not with any other reactant.

For a zero order reaction it would be M/s

The units for a zeroth order reaction is M/s, or mol/(L*s).

For a zero order reaction, the units for k is M/s. The general formula for units of k based on the order, where p is the order of the reaction, is M^(1-P)/s.

Zero order reaction units are in M/s.
