Given the equation 3A + B $\to$ C + D,you react 2 moles of A with 1 mole of B.Which of the following is true?
A)A is the limiting reactant because of its higher molar mass.
B)A is the limiting reactant because you need 3 moles of A and have 2.
C)B is the limiting reactant because you have fewer moles of B than A.
D)B is the limiting reactant because 3 A molecules react with 1 B molecule.
E)Neither reactant is limiting.

The equation shows that 3 moles of A are needed to react with 1 mole of B. However, we only have 2 moles of A and 1 mole of B, so we don't have enough A to completely react with the B. Therefore, A is the limiting reactant and B is in excess.
