Which one of the following is incorrect for ideal solution ?

Options

A. `Delta P=Pobs-P_("calculated by Raoult's law")=0`
B. `Delta G_(mix)=0`
C. `Delta H_(mix)=0`
D. `Delta U_(mix)=0`

Answer

B

Explanation

For an ideal solution `Delta H_(mix)=0`
`Delta U_(mix)=0`
`Delta S_(mix)ne 0`
According to `Delta G_(mix)=Delta H_(mix)-T Delta S_(mix)`
`rArr Delta G_(mix)ne 0`
Incorrect answer, is `Delta G_(mix)=0`
