QUESTION 4

Calculate the standard Gibbs free energy of rection at 650 K for the reaction

CO(g) + (1/2) O₂(g) → CO₂(g)

by assuming that the standard molar entalpy of the reaction is independent of the temperature.

AH (CO,g) = -110.5 kJ/mol;

Sᵒm(CO,g) 197.7 J/ (K mol)

AH (CO2.g) = -393.5 kJ/mol ;

Sºm (CO2.9) = 213.8 J/ (K mol)

Sᵒm(02.g) = 205.2 J/(K mol)

O a. 334,3 kJ/mol

O b.-257.2 kJ/mol

O c. -283.0 kJ/mol

O d. 25.77 kJ/mol

O e. -226.8 kJ/mol
