A chemically reactive system contains the following species in the gas phase: NH3, NO, NO2, O2, and H2O. Determine a complete set of independent reactions for this system. How many degrees of freedom does the system have?
Additional data: Use the Lee-Kesler graphs for enthalpy and entropy. The saturation pressure of propane at -51.4 °C is 0.66 bar. Take the ideal-gas CP of propane at these conditions to be constant and equal to 67 J/mole K.
Determine the molar free energy of vaporization, Delta vapG, for benzene at 75 C and 1 bar given that the molar enthalpy of vaporization of benzene at its normal boiling point of 80.09 C and 1 bar is 30.72 kJ⋅mol-1.
For a certain process, the maximum allowable pressure is 0.20 torr. If a D65 rotary vane pump is used and conductance losses in the vacuum system can be ignored; what is the maximum permissible inlet flow in standard cubic centimeters per minute?
