Question

Cinsider the production of carbon dioxideand methane from carbon monoxide and hydrogen:

2 CO (g) + 2H2 => CO2(g) + CH4 (g)

use the following data to calculate %u0394H, %u0394S, %u0394G for the reaction at 298 K. all value in the table are at 298 K

subsatance: CO(g) G2(g) CO2(g) CH4(g)

%u0394Hf (kJ/mol): -110.52 0 -393.5 -74.81

S initial(J/mol*K) 197.56 130.57 213.63 186.15

Part 2

Consider the following reaction CO(g) + H2(g) => HCHO(g) %u0394H initial= 1.96 kJ   %u0394S initial= 109.58 J/K

Calculate the change in entropy and predict the spontaniety of the reaction at 25 degrees Celcius.

Explanation / Answer

for the 2nd part, you must convert J/K to kj by dividing the j/K value by 1000.

G= (1.96) - (298)(.1096) = -30.7kj = since it is negative it will be non spon.
