Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Priyanshu kumar Best Answer
check this formula shristy
Increasing concentration and cationic charge...ionic strength increases ..which decreases the mean ionic activity coefficient..So option C and D is not possible
It increases with increase in dielectric constant
directly proportional but negative sign is there na shristy
option b is given in ans
yes it is right..
ionic strength is directly proportional to log y+- but overall negative sign is before log Y+-..so it reverse
ok sir
