If `D_(T)and D_(o)` are the theoretical and observed vapour densities at a definite temparature and `alpha` be the degree of dissocition of a substance ,then`aplha` in the terms of `D_(o),D_(T)` and n (number of moles of products formed formed from 1 mole reactant ) is calculated by the formula :
A
`alpha=(D_(o)-D_(T))/((1-n)D_(T))`
B
`alpha=(D_(T)-D_(o))/((n-1)D_(T))`
C
`alpha=(D_(T)-D_(o))/((n-1)D_(o))`
D
`alpha=(D-D_(T))/((n-1)D_(T))`
