PARTIAL EQUATION METHOD - EXAMPLE
In Partial equation method, the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations. The steps are:
The given chemical equation is split into two or more partial equations.
Each partial equation is separately balanced by the hit and trial method.
These balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations.
The balanced partial equations so obtained, are added to arrive at the balanced chemical equation
BALANCING OF CHEMICAL EQUATION BY PARTIAL EQUATION METHOD - DEFINITION
When equations contain many reactants and products they cannot be balanced by the hit and trial method. They are then balanced by the partial equation method. In this method the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations. The steps involved are:
The given chemical equation is split into two or more partial equations.
Each partial equation is separately balanced by the hit and trial method.
These balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations.
The balanced partial equations so obtained, are added to arrive at the balanced chemical equation.
