The heat capacity at constant pressure of hydrogen cyanide is given by the expression
Chapter 8, Problem 8.2(choose chapter or problem)
The heat capacity at constant pressure of hydrogen cyanide is given by the expression CpJ/molC 35:3 0:0291TC (a) Write an expression for the heat capacity at constant volume for HCN, assuming ideal-gas behavior. (b) Calculate H^(J/mol) for the constant-pressure process HCNv; 25C; 0:80 atm ! HCNv; 200C; 0:80 atm (c) Calculate U^(J/mol) for the constant-volume process HCNv; 25C; 50 m3 /kmol ! HCNv; 200C; 50 m3 /kmol (d) If the process of Part (b) were carried out in such a way that the initial and final pressures were each 0.80 atm but the pressure varied during the heating, the value of H^ would still be what you calculated assuming a constant pressure. Why is this so?
