By convention, the rate of the reaction is always positive and should be the same regardless
of the chemical species monitored. For the decomposition reaction given in #1 above,
2 H2O2 (aq) > 2 H2O (ℓ) + O2 (g)
Suppose you carried out the decomposition reaction using 35.0 mL of a 0.150 M hydrogen
peroxide solution and obtained the following results: 2.85 mL of (wet) oxygen gas is
formed in 90.0 seconds at 25 °C and a pressure of 760. Torr. The vapor pressure of water at
this temperature is 24 Torr.
A. What is the value for the average moles of oxygen gas produced per second?
(Hint: do not forget to correct for the fact that the gas is wet.)
B. What would be the concentration of oxygen if the gas remained in the solution and
was not allowed to escape?
C. Base on the above data, what is the rate of the reaction (in units of solution molarity
per second)?
