Identify the limiting reagent
« on: September 26, 2010, 10:33:50 PM »
I'm stumped on a question wanting me to find the limiting reagent between 3 different reactants:

3 TiO2 + 4 C + 6 Cl2 -----> 3 TiCl4 + 2 CO2 + 2 CO

with the moles being:

0.030 mol TiO2
0.042 mol C
0.066 mol Cl2

The question asks which one will be the limiting reagent. I sort of understand how to find the limiting reagent, when there are only 2 reactants.. not 3!


THANKS!!!

How do you work it, if there are only two reagents?

Well, I'm supposed to find the limiting reagent between the 3 reactants (TiO2, C, and Cl2). One will be all used up before the others... not sure which that is though...

You didn't get the hint.

If you take any two and ignore third for a moment - you will be able to calculate which one of the two is limiting. Then compare it with the third.
