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.

Answer:

I would say: D.

Explanation:

["Frequency is the number of times an object vibrates in 1 second; frequency is  also measured in hertz and is recognized by your ears as differences in pitch."] Frequency is how many times an object vibrates in ONE second. So that knocks the answer down to either A or B. Frequency itself is also measured in hertz, which knocks the answer to: D. hertz per second.
