Es
10 ml of a 3% hydrogen peroxide solution is added to five test tubes. as the hydrogen peroxide decomposes to produce
oxygen gas, the rate of oxygen production is rated on a scale of 0 - 5,0 meaning "no oxygen" and 5 meaning 'fast
to the other four test tubes of hydrogen peroxide, five drops of additional solutions are added. the solutions are indicated in the
data table as well as the rate of oxygen production for each
based on the data, what is the most appropriate conclusion for this experiment?
iron compounds are always used as catalysts,
reaction rate is always increased by iron compounds.
increasing the temperature increases the rate of decomposition
d)
iron compounds are a catalyst for the decomposition of hydrogen peroxide.
