From the phase diagram of water and an aqueous solution containing non-volatile solute, identify the incorrect option.

Answer»

At temperature `T_(0)`, vapour pressure of solid and vapour pressure of LIQUID will be same .
ORDER of vapour pressure `(P_(0),P_(1),P_(2))` are `P_(0) gt P_(1) gt P_(2)`.
`P_(0) = P_(2) e(DeltaH_("fusion")[T_(0)-T_(1)])/(T_(0)T_(1))`
`P_(1) = P_(2)e (DeltaH_(vap)[T_(0)-T_(1)])/(T_(0)T_(1))`
