How to calculate equivalent weight in disproportionate reaction

@ mahima 
in the case of disproportion reaction u can calculate the equivalent weight by the calculation of n factor . 
and for finding the n factor , use the following formula 
1/N= 1/n1 + 1/n2 
where 
n1 – n factor of oxidation half 
n2 = n factor of reduction half . 
and equivalent weight can be calculated by 
ATOMIC WEIGHT OR MOLECULAR WEIGHT / N FACTOR .
