Methanol is synthesized according to the following
reaction:
CO + 2H2 CH3OH
The standard heats of formation at 298 K are -110.6 kJ/mol. for CO,
-238.64 kJ/mol. for CH3OH. The latent heat of vaporization of
methanol at 298 K is 37.98 kJ/mol. The specific heats are (J/mol.
K) are given by:
Cp (CH3OH) = 18.382 + 101.564 x 10-3 T – 28.683 x 10-6 T2
Cp (CO) = 28.068 + 4.631 x 10-3 T – 2.5773 x 10-4 T2
Cp (H2) = 27.012 + 3.509 x 10-3 T – 6.9006 x 10-4 T2
Depict the standard heat of reaction at 9288 in K
