. Which one of the following is incorrect for ideal solution
A: P = Pobs - P calculated by Raoult's law = 0
B: Gmix = 0
C: Hmix = 0
D: Umix = 0
Best Answer
Explanation :
The correct answer is option B i.e. ∆G =0 is incorrect.
For the formation of any kind of mixture, change in Gibb's Free Energy should be negative i.e.∆G <0.
While for an ideal solution, change in enthalpy ( ∆H ), change in internal energy( ∆U ) as well as difference between expected and calculated values of pressure(Pobs - Pcal) =0.
Final Answer :
Thus, the correct answer amongst the following is option B i.e. ∆G is not equal to 0 for an ideal solution.
