2. What overall reaction order corresponds with a rate constant with units of M∙s^–1?

Thank you! :)

Answer 1

The reaction with an overall reaction order of 1 corresponds with a rate constant with units s⁻¹. The reaction with an overall reaction order of 0 corresponds with a rate constant with units M.s⁻¹.

Let's consider a generic reaction.

A ⇒ B

The generic rate law is:

$rate = k [A]^{x}$

where,

• rate: reaction rate

• k: rate constant

• [A]: molar concentration of the reactant

• x: reaction order for A

We can calculate the units of k using the following expression.

$[k] = M^{1-oro} /t$

where,

• oro: overall reaction order

1. What overall reaction order corresponds with a rate constant with units s⁻¹?

$[k] = M^{1-oro} /t = M^{1-1} /s = 1/s$

The overall reaction order is 1.

2. What overall reaction order corresponds with a rate constant with units of M∙s⁻¹?

$[k] = M^{1-oro} /t = M^{1-0} /s = M/s$

The overall reaction order is 0.

The reaction with an overall reaction order of 1 corresponds with a rate constant with units s⁻¹. The reaction with an overall reaction order of 0 corresponds with a rate constant with units M.s⁻¹.
