Cаlculаte the reаctiоn enthalpy fоr the fоllowing process at 1 bar and 298 K, then calculate it for 500K. The boiling point of methanol is 338K. All gases can be treated as ideal gases. The heat capacity of liquid methanol is 81.2 J/mol*K and the vaporization enthalphy is 35,200 J/mol. Part A. Use the tables from Module 0 to calculate the reaction enthalphy at 298K. Part B. Construct a thermodynamic pathway diagram for the contributing enthalpies to the reaction at 500K. Part C. There are 6 contributing enthalpies. Label them in your diagram in Part B and write the equations you can use to calculate them. Be sure to spell out what chemical entities your parameters refer to. Part D. Express the heat capacities for O2, CH2 and CH3OH gases in multiples of R assuming they can be treated as ideal gases. Part E. Calculate each of the 6 contributing enthalpies, and the total enthalpy of the process at 500K. Part F. Is the reaction at 500K endothermic or exothermic?
