Question 108

Question 108

Short Answer

Consider the reaction CO(g)+ 2H2(g)  Consider the reaction CO(g)+ 2H<sub>2</sub>(g)   CH<sub>3</sub>OH(l)at 25°C.  \Delta G°<sub>f</sub> (CO)= -137.3 kJ/mol  \Delta G°<sub>f</sub> (CH<sub>3</sub>OH)= -166.3 kJ/mol  \Delta H°<sub>f</sub> (CO)= -110.5 kJ/mol  \Delta H°<sub>f</sub> (CH<sub>3</sub>OH)= -238.7 kJ/mol S°(CO)= 197.9 J/K·mol S°(CH<sub>3</sub>OH)= 126.8 J/K·mol Calculate  \Delta G° at 25°C. CH3OH(l)at 25°C.
Δ\DeltaΔ G°f (CO)= -137.3 kJ/mol
Δ\DeltaΔ G°f (CH3OH)= -166.3 kJ/mol
Δ\DeltaΔ H°f (CO)= -110.5 kJ/mol
Δ\DeltaΔ H°f (CH3OH)= -238.7 kJ/mol
S°(CO)= 197.9 J/K·mol
S°(CH3OH)= 126.8 J/K·mol
Calculate Δ\DeltaΔ G° at 25°C.
