If above reaction is well-balanced then,
‘a’ moles of A reacts with ‘b’ moles of B to produce ‘c’ moles of C and ‘d’ moles of D.
Limiting reactant: It is reactant in a chemical reaction which limits the amount of products formed.
After complete utilization of limiting reactant, no more products are formed.
Way to determine limiting reactant:
- Calculate moles of each reactant.
- Divide moles of each reactant with their respective stoichiometric coefficient from well-balanced chemical equation.
- Lower value corresponds to the limiting reactant.

- 3.81 The particulate scale drawing shown depicts the products of a reaction between H2 and O2 molecules. (a) Draw a similar representation for the reactants that must have been present before the reaction took place. (b) Write a balanced chemical equation for the reaction, using the smallest possible whole number coefficients.arrow_forwardConsider the balanced chemical equation :math>A+5B3C+4D en equal masses of A and B are reacted, which is limiting, A or B? Justify your choice. If the molar mass of A is greater than the molar mass of B, then A must be limiting. If the molar mass of A is less than the molar mass of B, then A must be limiting. If the molar mass of A is greater than the molar mass of B, then B must be limiting. If the molar mass of A is less than the molar mass of B, then B must be limiting.arrow_forwardBalance the following chemical equation, and then answer the question below. :math>CuSO4(aq)+KI(s)CuI(s)+I2(s)+K2SO4(aq) ich reactant is the limiting reactant? Choose the best answer. th CuSO4and Kl are equally limiting because they react in a 1:1 mole ratio. i>CuSO4is the limiting reactant because only 2 moles are available compared with 4 moles of Kl. i>Kl is the limiting reactant because it is present in excess. i>Neither CuSO4 nor Kl is a limiting reactant because 6 total moles are present on the reactant side compared with 5 total moles on the product side. i>The limiting reactant cannot be determined because the starting amounts are not given.arrow_forward
