The volumetric analysis of a gas mixture is 30 percent oxygen, 40 percent nitrogen, 10 percent carbon dioxide, and 20 percent methane. This mixture is heated from 20C to 200C while flowing through a tube in which the pressure is maintained at 5 MPa. Determine the heat transfer considering that the mixture is: a) Gas ideal q kJ/mol b) Gas real con la regla de Kay 4- kJ/mol q=
