PIEAS MS CHEMISTRY Fellowship Past Papers 2022

MS  Chemistry Fellowship Test (23-07-2022):

Test was quite difficult and main part of test is physical chemistry.

Mostly questions are concerned with enthalpy and entropy

And the named reaction are also there.

And numerical portion was difficult and time taking.
