This is a limiting reagent problem. You know that because amount are given for BOTH reactants. BUT you don't list the reactant besides O2.
So what is the answer?
Did you read my response? You didn't list the reactants. You listed O2 but not the other material.
How many liters of Co2(g) can be produced in the reaction of 5.24 L C O (g) and 2.65 L O2 (g) if all these gases are measure at the temperature and pressure?
Thanks and My apologies
I suppose you mean at the "same" T and P.
2CO + O2 ==> 2CO2
When gases are involved one need not convert to mols but may use L directly.
Since this is a limiting reagent (LR) problem you must first determine the LR.
Convert L CO to L CO2. Do the same for L O2 to L CO2.
5.24L CO x (2 mols CO2/2 mols CO) = 5.24 x 2/2 = 5.24 L CO2b produced if you had 5.24 L CO and all of the O2 you needed.
2.65 L O2 x (2 mols CO2/1 mol O2) = 2.65 x 2/1 = 5.30 L CO2 produced if you had 2.65 L O2 and all of the CO you needed.
You see the two answers are not the same which means one of them is wrong. The correct value in limiting reagent problems is ALWAYS the smaller value. SO 5.24 L CO2 is the correct value.
Ok thanks.
2.65 L O2 x (2 mols CO2/1 mol O2) = 2.65 x 2/1 = 5.30 L CO2. is this the correct answer?
No. We must not be on the same wavelength. Here is what I wrote.
You see the two answers are not the same which means one of them is wrong. The correct value in limiting reagent problems is ALWAYS the smaller value. SO 5.24 L CO2 is the correct value.
