Question

The rate law of a reaction is rate = k[D][X]. The units of the rate constant are ________.
a. mol² L⁻²s⁻¹
b. mol L⁻¹s⁻²
c. mol L⁻¹s⁻¹ L
d. mol⁻¹s⁻¹ L²
e. mol⁻²s⁻¹

Answer 1

Answer:

D

Explanation:

Hello!

Since the rate must have the following units: mol/(L*s), the suitable units for k, considering that the term [D] [X] leads to mol^2/(L^2) (it means a second order kinetic law), are L/(mol*s), nevertheless, that answer isn't in the given options.
