86. Calculate the entropy of the reaction 2H2 (g) CO (g) → CH3OH (g) at temperatures of 298.15 and 1000K, using the absolute entropy of the compounds at T = 298.15 and p = 1 atm.: S0cn3OH = 239.76 J / mol ∙ K, S0H2 = 130.52 J / mol ∙ K, S0СО = 197.55 J / mol ∙ K.
The dependence of heat capacity on temperature is expressed by the equations:
Ср (CH3OH) = 〖15.28 105.20 ∙ 10〗 ^ (- 3) T-31.04 ∙ 〖10〗 ^ (- 6) T ^ 2J / mol ∙ K
Ср (H2) = 〖27.28 3.26 ∙ 10〗 ^ (- 3) T 0.50 ∙ 〖10〗 ^ 5 T ^ (- 2) J / mol ∙ K
Ср (CO) = 〖28.41 4.10 ∙ 10〗 ^ (- 3) T-0.46 ∙ 〖10〗 ^ 5 T ^ (- 2) J / mol ∙ K
