Question
Initial rate of rxn of H2O2(aq)->H2O+ 1/2 O2(g) is found at 1.7x10(-3)M/s and is constant for 2min. You start with 160ml of 16M H2O2.
How many mL of O2 in one minute? (Measured at 273K and 760mmHg).
I tried to find the new conc of H2O2 via NewConc= Old conc - kt
Then i multiplied the new conc by .16L, converted those moles to O2 and solved for volume via the PV=nRT, but ended up with 2.3ishL, which seems rather large considering it's asking for V in mL. Any idea if this is right or not?
(I doubt i can assume the volume is constant in my method, among all the other things most likely wrong with it XD)
Thanks!

you did not balance the equation first. it is rather difficult to react 1/2 an atom.

No it's balanced. you're allowed to have fractions in the equation. Uncommon yes, but not impossible. Nice try though :P
