- What is the value of ln y (where y = activity co-efficient) for ideal gases?
Answer : Option A
Explanation :
Since activity co-efficient is defined as
γi=Fugacity in real solutionFugacity in ideal solution,lnγ1=¯nGElRT=0(for ideal solution),
Since there will be no excess gibbs free energy for ideal solution.
So, in the question it will be better if replace ideal gas by ideal solution.
