0.12

Explanation:

The rate law of the given reaction is:-

Rate=k[A][B]

Wherem, k is the rate constant.

Given that:-

Rate = 0.36 mol/Lsec = 0.36 M/sec

[A] = 3.0 M

[B] = 1.0 M

Thus,

Applying in the equation as:-

0.36 M/sec = k * 3.0 M * 1.0 M

k = 0.12 (Ms) ⁻¹

The numerical value of k, the rate constant, is closest to 0.12.
