Product description
13. For a given reaction and under given external conditions (options for setting the reaction and conditions, reference materials in the attached file), determine:
1. Thermal effect of the reaction at constant pressure and temperature of 298 K.
2. Thermal effect of the reaction at a constant volume and a temperature of 298 K.
3. Thermal effect of the reaction at constant pressure and temperature specified in the condition.
4. Entropy change during a reaction at a temperature of 298 K.
5. The change in entropy during the reaction at a given temperature in the condition.
6. Standard change in Gibbs energy at T=298 K.
7. Standard change in Helmholtz energy at T=298 K.
8. Standard change in the Gibbs energy at a given temperature in the condition (Tyomkin-Schwartzman method).
9. The equilibrium constant of the reaction at a given temperature in the condition (to conclude that the reaction is complete).
10. Non-standard change in the Gibbs energy (isotherm equation) at the temperature and composition of the gas phase specified in the condition (to conclude that the reaction is thermodynamically possible in the forward direction).
The total pressure in the system is 1 atm. In the presence of one reacting gas, the remaining pressure is created by an inert gas.
