Question

Everything needed is included. This is NOT graded, it is for practice. No grade is given for this. It is an old practice exam. 

The oxidation of carbon monoxide is important in reducing ground-level pollution from cars:

CO(g) + 1/2 O2 (g) −−→ CO2 (g)                                   (1)

Use the information you have available to answer the following questions.

3a. What is the molar enthalpy of reaction (∆H◦ rxn) for Equation 1 at a temperature of 298 K? 

3b. This reaction is typically run using a catalyst at elevated temperature. What is the value of ∆H◦ rxn for Equation 1 at a temperature of 700 K? 

3c. Give the molar internal energy of reaction (∆U ◦ rxn) at 700 K for Equation 1.
