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?

Correct Answer: C. Reactant A and B

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.
