Chemistry

A sample containing 321.5 g of nitrogen gas is expandedisothermally at T=298 K from 1.023dm^3 to 57.28dm^3. Calculate q,w, delta U and delta H for four processes assuming N^2 behavesideally:

(a.) in a vacuum

(b.) against a constant external pressure equal to the finalpressure of the sample

(c.) reversibly
