When equal moles of reactant A and B are allowed to react according to the following balanced equation (2 A + B __> Product). The limiting reactant in this chemical equation will be?

A. Reactant A
B. Reactant B
C. Reactant A and B
D. No Limiting Reactant

Answer

Correct Answer: C. Reactant A and B

Detail about MCQs

To determine the limiting reactant, you need to compare the stoichiometric coefficients of the reactants in the balanced chemical equation to the initial moles of each reactant.

The balanced equation is: 2A + B -> Product

If you have equal moles of reactant A and B, this means you have a 1:1 mole ratio of A to B. In this case, neither A nor B is in excess, and they are both reacting in a 1:1 ratio as required by the equation.

So, the correct answer is: C. Reactant A and B

Both reactant A and reactant B are limiting reactants in this scenario because they are consumed in equal amounts to form the product.
