Q23 / 160 · NTA Abhyas (NEET) 2020 · Chemistry · Solutions

Which one is not equal to zero for an ideal solution

  • Correct answer
    A
    ΔSmix
  • B
    ΔVmix
  • C
    ΔP=Pobserved-PRaoult
  • D
    ΔHmix

Solution

For an ideal solution ΔSmix>0 as in order to maintain spontaneity ΔSmix must be positive. for ideal solution ΔVmix , ΔHmix and ΔP=Pobserved-PRaoult are zero.

Hence, the correct answer is option: 'A'.
