limiting reactant help
« on: October 11, 2009, 12:41:30 PM »
Here's the balanced equation:

2S + 3O2  :rarrow: 2SO3


And the question is:

For each of the given situations, indicate whether S or O2 is the limiting reactant:

* 3 mol S and 5 mol O2
* 3 mol S and 4 mol O2
* 3 mol S and 3 mol O2


The answers are:

* S is the limiting reactant
* O2 is the limiting reactant
* O2 is the limiting reactant


My question - can someone please show me the solution? It's probably easy but I can't figure it out. Thank you. :)




Note: This is a 3-part question and this is Part 3 so I may have missed out on posting some other relevant info.
