Neet Solved Paper 2015 Question 16
Question: Which one is not equal to zero for an ideal solution?
Options:
A) $ \Delta H _{mix} $
B) $ \Delta S _{mix} $
C) $ \Delta V _{mix} $
D) $ \Delta P=P _{observed}-,P _{Raoult} $
Show Answer
Answer:
Correct Answer: B
Solution:
For an ideal solution ..(i)
There will no change in volume on mixing the two components
i.e. $ \Delta V _{mixing}=0 $ ..(ii)
There will no change in volume on $ \Delta H _{mixing}=0 $
so, $ \Delta S _{mix}\ne 0 $ an ideal solution.
