CH 14
The reaction2H2O2(aq)â†’2H2O(l)+O2(g) isfirst order in H2O2 and under certain conditions has a rateconstant of 0.00752 sâˆ’1 at 20.0 âˆ˜C. A reaction vessel initiallycontains 150.0 mL of 30.0% H2O2 by mass solution (the density ofthe solution is 1.11 g/mL). The gaseous oxygen is collected overwater at 20.0 âˆ˜C as it forms.
What volume of O2 will form in 83.2 seconds at abarometric pressure of 725.2 mmHg . (The vapor pressure of water atthis temperature is 17.5 mmHg)
