Lesson: Relative Reaction RatesChemistry
In this lesson, we will learn how to use changes in concentration, pressure, conductivity, and optical absorption to calculate relative reaction rates.

The rate of a reaction doubles for every increase in temperature.
If the temperature increases from to , by what factor does the reaction rate change?
If the temperature decreases from 95 to , by what factor does the reaction rate change?
Carbon monoxide reacts with nitrogen dioxide to form carbon dioxide and nitric oxide, as shown.
The rate law for this reaction is rate = and the reactants have a constant temperature and total volume.
By what factor does the rate change if the pressure of decreases from 0.500 atm to 0.250 atm?
By what factor does the rate change if the concentration of changes from 0.010 M to 0.030 M?
Bromide and bromate(V) ions react in acidic aqueous solution to form elemental bromine, as shown.
The initial reaction rate of hydrogen ions is M/s. What is the initial reaction rate of bromide ions?
Over the first 3.00 minutes of the reaction, elemental bromine is formed at an average rate of M/s. The pH at the start of the reaction is 2.30. Calculate the pH after 3.00 minutes.
