Respuesta :
The reaction rate is the rate at which the reaction takes place and results in an increased concentration of the products. The rate of the reaction is 0.0123 M/s.
What is the reaction rate?
The reaction rate is the increase of the concentration of the product with respect to time in seconds. The rate of reaction is given by,
[tex]\rm rate = \rm \dfrac {\Delta C}{\Delta t}[/tex]
Given,
Change in product concentration = 1.478
Time period = 120 seconds
Substituting values in the above equation:
[tex]\begin{aligned} \rm rate &= \rm \dfrac {\Delta C}{\Delta t}\\\\& = \dfrac{1.478}{120}\\\\&= 0.0123 \end{aligned}[/tex]
Therefore, option B. 0.0123 M/s is the reaction rate.
