Nonideal Gas Equation : The SRK equation is a commonly used equation of state that relates the absolute temperature T, the absolute pressure P, and the molar volume V of a gas under conditions in which the behavior of the gas connot be considered ideal (e.g. moderate temp. and high pressure). Tc: The critical temp. of the gas = 405.5K. Pc: the critical pressure of the gas=111.3 atm, and w is the Pitzer acentric factor=0.25. Each of these is readily available for many gases. Calculate the pressure exerted by 20 gram-moles of ammonia at 300 K in a 5-liter container, using : a. the ideal gas equation b. the SRK equation
