NOT correct! :-)
But apart from that so far you did well ... :)
Edit: by the way, the reaction speed v is not negative (even if ∆c is negative), but that's not the point: your number is wrong, too.

humm... if you are expecting the answer in concentration:
[CO2] = 4.734 x 10-2 mol dm-3
implies rate of CO2 production = 6.7 x 10-3 mol dm-3 hr-1
implies speed of dissipating isooctane = 8.37 x 10-4 mol dm-3 hr-1
Thanks for letting us know about the concentration of carbon dioxide.
How exactly do you get
c(CO2) = 4.734 x 10-2 mol/dm3?
Nah.... sorry for getting so many typo
[CO2] = 1596.78 mol / 3.92 x 10 4 dm3
= 4.0734 x 10-2 mol dm-3
But the rest should be the same
:)
This result is the (lower) concentration of CO2 when it was emitted as a gas already ... but gasoline is a liquid ...
Ya, so why I am wondering what unit you are expecting
Speed of reaction: defined as how quickly or slowly a reaction takes place
(So my very initial attempt was in liter per hour)
As you wrote yourself, reaction speed is measured in v = ∆c/∆t (and if it is an educt: v = - ∆c/∆t, because ∆c is negative, so with the additional minus v itself stays positive).
But as you said, the gasoline is a liquid, and the concentration of a liquid is constant, so ∆c would be zero, so you expect v to be zero in my answer?
