Summary: FORMULAE SHEET
General Balance Equation
ACCUMULATION=INPUT-OUTPUT+GENERATION-CONSUMPTION
Balance on Continuous Steady State Processes
INPUT+GENERATION =OUTPUT+CONSUMPTION
Limiting Reactant: A reactant is limiting if it is present in less than its stoichiometric proportion relative
to every other reactant.
Fractional Excess: Fractional Excess =

where n is the amount of the limiting reactant fed and ns is the stoichiometric
amount.
Percentage Excess: Percentage Excess = 100 * Fractional Excess
Fractional Conversion: f
