Given for problems: 1) Conversion method for Gibbs Free Energy (GSE) Write the relation. Explain its purpose. ( 10 points ) AH 20 or(CO )= -94,050 Kcal/mol AH 203 or(CO)= -26,400 Kcal/mol AH 20 or(H2O) = -57,800 Kcal/mol AH 20 or(CH4)= -17,890 Kcal/mol 2) For an ideal gas, Entropy is the volume and temperature Write the relation showing that it has a function Constant gas temperature in volume condition from 25. C to 100.C is removed. Entropy change of gas calculate. Given: Cp-R-4. (5 + 10) C(CO )= 10.55 +2.16x10 - T C(CO)- 6.79 +0.98x10 T C>(H2O) = 7.17 +2.56x10T C(CH4)=5.65 + 11.44x10 - T C (0)= 7.16 + 1.00x10T C (N 2 )= 6.66 + 1.02x10 - T C>(H)- 6.92 +1.00x10 T 3) 1x10 6 mol CH 4 in a heat power plant under standard condition it is burned with full air. The combustion system reaches temperature about 2000. C, the heat energy obtained It has been measured as 1.92x10 11 cal. 90% of heat efficiently in a unit producing mechanical work is wasted, only 10% of the heat lost from the chimney It is discarded as. Under these conditions, CH 4 gas Calculate the calorific power per mole.
