The overall ionic reaction for the decomposition of bleach with a cobalt (II) nitrate catalyst is shown
below:

2 Na1+(aq) + 2ClO1−(aq)  (Co2+)→ 2 Na1+(aq) + 2Cl1−(aq) + O2(g)



a) REVIEW: Write the net ionic equation for this reaction.

b) In a test trial, using 6% extra strength bleach at room temperature, 100.0 mL of oxygen gas was
produced in 2.03 seconds. Calculate the average reaction rate for the oxygen gas.

c) This reaction produced the gas too fast to record useful data. State two ways to slow this reaction
down and explain how those factors cause the rate to decrease.
