Orders and Rates

[lilliewasem_2G]

Why does each order have different units and does it impact the overall k value?

The orders have different units because of the concentration per unit of time.

The units for each reaction order are different because the reaction rate is defined in units of concentration per unit of time.

[Ishita S 2E]

The units of K, the rate constant, change depending on the order of the overall reaction. This is because the reaction rate always has units of M/s or mol(L^-1)(s^-1). Thus, the units of K have to be adjusted to account for its multiplication with zero, one, or more reactant concentrations in the differential rate law so that the reaction rate ends up with the correct units.

Each order has different units each reaction order corresponds to different mathematical relationship between concentration of the reactants and the reaction rate. The reaction rate depends on the concentration per unit time which allows it to change for every order of reactions, thus leading the k constant to change as well.
