Answer:
Explanation:
You can infere the units of the rate constant for an <em>overall order 2 reaction </em>departing from the simplified case of a two identical reactants combined in a single elementary step:
- A + A → Products (single elementary step equation)
For that equation the differenttial form of the rate of reaction is:
- r = - d [A] / dt = K [A]²
The units of [A] are M¹ (i.e. M), and the units of - d [A] / dt are M¹ s⁻¹ . . . ( M stands for molar concentration)
Substituting the unis on both sides of the rate equation you get:
Solving for K:
- K = M¹ s⁻¹ M⁻² = M⁻¹ s⁻¹, which is the final result.
