Consider the following reaction; 3A+B--3C, where 2 moles of A react with 1 mol of B to completion? Which of the statement is correct?
1) B is the limiting reactant because you have fewer mole B than A
2) a is the limiting reactant because 2 moles of a will react with 1/3 mole of B
3) A is in excess
4) B is the limiting reactant
