Large amounts of nitrogen gas are used in the manufacture of ammonia, principally for use in fertilizers. Suppose 120.00 kg of N2 (g) is stored in a 1100.0-L metal cylinder at 280oC.
(a) Calculate the pressure of the gas, assuming ideal-gas behavior.
(b) By using data in Table 10.3, calculate the pressure of the gas according to the van der Waals equation.
(c) Under the conditions of this problem, which correction dominates the one for finite volume of gas molecules or the one for attractive interactions?
