Question
(1) Consider an equilibrium gas phase containing (only) solid C(s) and a gas phase containing only co CO2, H2, H20 (a) How may degrees of freedom for this system? (Report P,C,F). If T 1090 K and PT 1 atm how many degrees of freedom are left (F' (b) How many independent, balanced chemical reactions exist among the named species? Write the reactions. Calculate the numerical value for K for each reaction, and write K as a function of the equilibrium gas-phase partial pressures: pco,pco etc. ("Simple" equations are best for Part (c) Data K. formation, 1090 CO 1.2x1010 CO2 1.0x1019 H20 1.1x109 C(s) 1 (c) Given the results from (b) and pH2 0.40 atm in the equilibrium system. T. 1090 K. T- 1090 K. PT 1 atm PT 1 atm 0.70 pco pco pCO2 0.40 pH2. pH2. PH20 excess solid carbon (C excess solid carbon (C) calculate the unknown pi pco pco2 pH20 (Hint: 0.40Explanation / Answer
Degrees of Freedom F=C-P+2
here (C) components are five i.e solid C,CO2,CO,H2,H20, But phases are two only those are solid and gas
so F=5-2+2
F=5
