One of the many reactions which occur when iron ore is smelted in a blast furnace is given below. for this reaction, the equilibrium constant in terms of partial pressures, kp, is 0.900 at 873 k and 0.396 at 1273 k. assume the reaction takes place in a vessel containing only product and reactant molecules and that ah and as do not change with temperature. feo(s) + co(g) = fe(s) + co2(g) a) calculate ah, ag and as for the reaction at 873 k b) what is the mole fraction of co2(g) at 873 k? include only the gas-phase species in this mole fraction.

Explanation: AH, AG and AS for the reaction at 873 K

delta G =-RT ln Kp

G= -8.314 x 873 ln 0.9

= 764.7J/mol

AG = AH-TAS

AH = 764.7 - 8314(0.9)

Kp =pCO/pCo2

Substitute the values at different temp. Solve simultaneously

Since mole fraction =kp/pCo

Mf =1.5

I think it’s Truth because artificial ingredients tend to be cheaper than the organic ingredients
