Ideal Gas Law and Diffrentiation

[SiddR]

Is it possible to calculate the rate of change of n with respect to rate of change of Pressure and rate of change of Temperature with V unknown but constant by PV = nRT?

Rate of change of Pressure and rate of change of temperature can be measured. R and V are constants.

No, it is not possible to calculate the rate of change of both n and T with respect to V unless there is some additional relation between n and T. In general, it is not possible to find two different things given one piece of information (here that "piece of information" is the gas law).
