Calculate the entropy change AS universe for the following reaction, at 25 C.
CO + 2H2
CH,OH
Standard entropy, AS
CO 197.7 J/mol-K
Ha = 130.7 J/mol-K
CH,OH = 127.2 J/mol-K
Standard enthalpy of formation, AH?
CO -110.5 kJ/mol
H2 = 0 kJ/mol
CH3OHm = -238.4 kJ/mol
b. From the calculated entropy change value, what can you conclude
regarding the process?
