For the reaction 2CH C2H6 g) Ha the standard change in Gibbs free energy is AG 3-32.8 kJ/mol. What is AG for this reaction at 298 K when the partial pressures are Pc 0.250 atm, P 0.150 atm and PCH, 0.850 atm Number k J/ mol AG I'm Cortana. Ask me anything.

A A EMPERAURE OF 2980 K, AND A A PARIAL PRESSURE OF 1 Am,
C2H6 (g) + H2 (g) = 2 CH4 (g) + 32.8 KJ / mol
in he above reacion,
PC2H6 + PH2 = PCH4
AND ALSO
1 MOLE OF C2H6 REACS WIH 1 MOLE OF H2 O FORM 2 MOLES OF CH4
AS PER DALON'S LAW OF PARIAL PRESSURES,
KC2H6 *PC2H6 +KH2 * PH2 = KCH4 * PCH4
WHERE K IS MOLE FRACION.
HE EQUAION, A + B = C + D
FOR A GIBBS FREE ENERGY IS
DELA G = DELA G0 + R ln [ (PC * PD) / ( PA * PB ) ]
FOR HE PRESEN REACION
DELA G = - 32.8 + 8.314 * 298 [ 0.8502 ] / [ 0.250 * 0.150]
= 32.8 + 47.73
= 80.53 K J / mol
