Identify the false statement among the following.
Options
- AIdeal solution obey Raoult's law over entire range of temperature and concentration.
- BFor ideal solution _ mix V =0 .
- CNon ideal solution do not obey Raoult's law over the entire range of concentration.
- DVapour pressure of non ideal solution always lies between vapour pressure of pure components.
Correct answer
D. Vapour pressure of non ideal solution always lies between vapour pressure of pure components.
Step-by-step solution
- (1) Ideal solution obey Raoult's law over the entire range of temperature and concentration: This is true. An ideal solution is one in which the intermolecular interactions between the components are identical to those between the molecules of the individual components. As a result, an ideal solution obeys Raoult's law over the entire range of concentrations and temperatures. - (2) For ideal solution, V =0 : This is true. In an ideal solution, the volume change upon mixing ( V ) is zero, meaning the total volume
