Stoichiometry
Prepared by Raja Wajahat 31
Stoichiometry
Stoichiometry Deals with combining weights of elements and compounds
Stoichiometric Ratios are obtained by dividing the numerical coefficients in the chemical
equation
From these ratios we can calculate No. of moles of one substance as related to the no of
moles of another substance

Prepared by Raja Wajahat 46
The Material Balance Equation
Steady State System – Accumulation = 0
Non Reactive Process – Generation= Consumption= 0
Closed System – Input= Output= 0
Prepared by Raja Wajahat 47
The Material Balance Equation
Differential Balance = defines the system at that very INSTANT
All quantities are defined in rates [g/s, lb/hr]
Used for continuous processes
Integral Balance = Defines the system between two instants of time
All quantities are defined in amounts [g, hr]
Used for batch processes
