b)gretar than 1
c)equl to 1
d)non of the above​

Answer 1

your answer is greater than 1

Answer 2

The activity coefficient for a non-ideal solution is less than 1 (option-a).

• Effective concentration of a solute or solvent in a mixture is called the activity of that solution.
• It can be 1, less than 1 i.e. negative, and greater than one.

• Its value is negative or less than 1 when there is a negative deviation from the ideal behavior.

• And, greater than 1, means positive when there is a positive deviation from the ideal condition.
• As there is a negative deviation, in the case of the non-ideal solution, therefore its activity coefficient is less than one or negative.
