Fundamental of Material Balance for Reactive Process

Limiting reactant is

• reactant that its present is less than its stoichiometric proportion relative to every other reactant

• reactant that would be first fully consumed / reacted

• reactant that controls the reaction to complete reaction

• reactant that has more control of the reaction than fractional conversion
