Suppose you carried out the decomposition reaction using 30.0 mL of reaction solution (i.e. 15.0 mL of 6.0% hydrogen peroxide and 15.0 mL of the solvent, water) and obtained the following results: a pressure change of 0.087 atm was observed over a period of 11.0 seconds, and the temperature was constant at 22.5ºC.
A. How many moles of oxygen gas are produced in 11.0 seconds? (You will want to use your conversion factor from question 1.)
B. What would be the concentration of oxygen (in molarity units) if the gas had remained in the solution?
C. Based on the above data, what is the rate of the reaction (in units of solution molarity per second)?
