g What is the half-life for a particular reaction if the rate law is rate = (1291 M⁻¹*min⁻¹)[A]² and the initial concentration o

Gnoma [55]

Answer:

$t_{1/2}=3.10x10^{-3}min=0.186s$

Explanation:

Hello,

In this case, for the calculation of the half-life for the mentioned reaction we first must realize that considering the units of the rate constant and the form of the rate law, it is a second-order reaction, therefore, the half-life expression is:

$t_{1/2}=\frac{1}{k[A]_0}$

Therefore, we obtain:

$t_{1/2}=\frac{1}{1291\frac{1}{M*min}*0.250M}\\\\t_{1/2}=3.10x10^{-3}min=0.186s$

Regards.
