This question is driving me crazy. I don't necessarily want all of the steps, just a push in the right direction. Thankyou.
A natural gas mixture is burned in a furnace at a powergenerating station at a rate of 13.0 mol per minute. (a) If the fuel consists of 9.3 mol CH4, 3.1 mol C2H6, 0.40 mol C3H8, and 0,20 mol C4H10, what mass of CO2(g) is produced per minute? (b) How much heat is released per minute?
So what immediately struck me is that part (a) could be determined by normal stoichiometric methods, but the rate part is confusing me. Also I am not sure how to get the heat from

Best ResponseYou've already chosen the best response.1Since the information is given as a rate (gas mixture burnt at 13.0 mol per minute) when you calculate the mass of CO2 the answer will also be a rate. For the heat you will either need to use bond enthalpies (from tables) and calculate that.

Best ResponseYou've already chosen the best response.0Ok, so bond enthalpies, not standard enthalpies of formation?

Best ResponseYou've already chosen the best response.1You can use standard enthalpies of formation as well. They should give you approximately the same answer.
