statements is correct regarding the behaviour of the solution ?
Choose an option
Show full solutionCorrect option: B
Correct answer
BThe solution is non-ideal, showing +ve deviation from Raoult’s law.
Step-by-step explanation
For this solution intermolecular interactions between -heptane and ethanol aare weaker than -heptane -- heptane & ethanol-ethanol interactions hence the solution of -heptane and ethanol is non-ideal and shows positive deviation from Raoult's law.
