Answer:
2.3*10^-19 M/s
Explanation:
Generally, reaction rate is the product of the rate constant, and the concentrations of the reactants in the system. Therefore, the rate of the reaction can be expressed as:
rate = k*![[CF_{3}CH_{2}F][OH]](https://tex.z-dn.net/?f=%5BCF_%7B3%7DCH_%7B2%7DF%5D%5BOH%5D)
The value of the rate constant k is 1.6*10^8 [1/(M*s)] at the given temperature.
= 6.3*10^8 molecules/cm^3
= 8.1*10^5 molecules/cm^3.
However, we need to convert to mol/(L(M). Therefore:
6.3*10^8 *(1000/6.023*10^23) = 1.05*10^-12
8.1*10^5 molecules/cm^3 *(1000/6.023*10^23) = 1.3*10^-15
Thus:
rate =k*
= 1.6*10^8* 1.05*10^-12* 1.3*10^-15 =2.3*10^-19 M/s
