40. Решение задачи по химии №004 139

7. For the proposed reaction, answer the following questions:
- Exo- or endothermic is this reaction; determine the thermal effect of the formation of 1 kg of any of the reaction products;
How does the degree of disorder change during a reaction?
- whether this reaction is possible in an isolated system under standard conditions;
- what factor (entopic or enthalpic) contributes to the process;
- write down the expressions for kinetic and thermodynamic equilibrium, show the relationship between them;
- calculate the numerical value of equilibrium at a temperature of 20 C and 1000 K. At what temperature is the completeness of the reaction higher;
- indicate the conditions under which the equilibrium is shifted in the forward direction, using the principle of Le Chatelier.
