The average reaction rate during that time period is 0.0025 mol/l.
What is concentration?
The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution.
Given data:
[tex]t_1[/tex] = 10 seconds
[tex]t_2[/tex] = 20 seconds
[tex]C_1[/tex] = 0.210 mol/L
[tex]C_2[/tex] = 0.185 mol/L
∆C = |[tex]C_2[/tex]–[tex]C_1[/tex]| = |0.185-0.21| = 0.025 mol/l
∆t = [tex]t_2[/tex]– [tex]t_1[/tex] = 20 - 10 = 10 sec
∆C — is the concentration change
∆t — is the time change
V — reaction rate
V= [tex]\frac{\Delta C}{\Delta t}[/tex] = [tex]\frac {0.025}{10}[/tex]= 0.0025 mol/l•sec
Hence, 0.0025 mol/l is the average reaction rate during that time period.
