3. According to the Kirchhoff equation, the heat of reaction at constant pressure and a given temperature
4. Change in the entropy of the system at T = 298
5. Change in the enthalpy of the system at a given temperature.
6. Change in the Gibbs energy at T = 298 K
7. Change in the Helmholtz energy at T = 298 K
8. According to the Temkin-Schwartzman equation, change in the Gibbs energy at a given temperature.
9. The equilibrium constant of the reaction and draw a conclusion about the completeness of the process.
10. According to the reaction isotherm equation, change in the Gibbs energy under given conditions and draw a conclusion about the direction of the process.
