Define (i) cryoscopic constant (ii) ebullioscopic constant

Explanation

(i) `Delta T_(f) = k _(f) . M,` where `k _(f)=` cryscopic constant
If `m =1,` then `Delta T_(f) = k _(f)`
`k_(f)` is defined as depression in freezing point for 1 molar solution.
(ii) `Delta T_(b)= k _(b) .` m where `k _(b)` = ebullioscopic constnat
If `m =1,` then `Delta T_(b)= k _(b)`
`k _(b)` is defined as elevation in bliling point for 1 molar solution.
