(a)
Interpretation: To determine the limiting reactant in the given mixture of reactants.
Concept Introduction :
A
Let’s say we have a
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.
(b)
Interpretation: To determine the limiting reactant in the given mixture of reactants.
Concept Introduction :
A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.
