Question

The rate constant of a reaction has same units as the rate of reaction. The reaction is of ____________.

Options

• zero order

• first order

• second order

• third order

Answer 1

The rate constant of a reaction has same units as the rate of reaction. The reaction is of zero order.

Explanation:

For a zero order reaction, the rate law is

rate = k [A]⁰ = k = `-("d"["A"])/"dt"`

As a result, the units of the rate constant and the rate of the reaction are the same for a zero order reaction.
