Unformatted text preview: ionizes according to the reaction Na Na e at 2000 K and 0.8 atm (KP 0.668 for this reaction). Answer: 67.5 percent 1632 Liquid propane (C3H8) enters a combustion chamber at 25C at a rate of 1.2 kg/min where it is mixed and burned with 150 percent excess air that enters the combustion chamber at 12C. If the combustion gases consist of CO2, H2O, CO, O2, and N2 that exit at 1200 K and 2 atm, determine Chapter 16
1638C What is the equilibrium criterion for systems that involve two or more simultaneous chemical reactions? 1639C When determining the equilibrium composition of a mixture involving simultaneous reactions, how would you determine the number of KP relations needed? 1640 One mole of H2O is heated to 3400 K at a pressure of 1 atm. Determine the equilibrium composition, assuming that only H2O, OH, O2, and H2 are present. Answers: 0.574H2O,
0.308H2, 0.095O2, 0.236OH | 819 Ethyl alcohol (C2H5OH(g)) at 25C is burned in a steady-flow adiabatic combustion chamber with 40 percent excess air that also enters at 25C. Determine the adiabatic flame temperature of the products at 1 atm assuming the significant equilibrium reactions are CO2 CO 1 1 1 N...
