mol7. Find the percent hydrogen peroxide.
8. You can also easily determine the reaction rate. To do this, divide the total volume of oxygen collected by the total time of the reaction.
Post-lab Questions1. Was the calculated percentage of hydrogen peroxide close to the same as the percentage on the label?
2. Considering that catalysts are not consumed in a reaction, how do you think increasing the amount of catalyst would affect the reaction rate for the decomposition of hydrogen peroxide?
