Hydrogen and iodine gas react to form hydrogen iodide, as shown in the equation H2(g) + I2(g) → 2HI(g). Suppose you are given a time interval from t1 = 10 seconds to t2 = 20 seconds and a change in H2 concentration from0.210 mol/L to 0.185 mol/L. Use the reaction rate equation to calculate the average reaction rate during that time period. Show your work.

Sagot :

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.
