77. Solving a chemistry problem

4. Calculate the thermal effect (enthalpy change) of the reaction according to the following experimental data given in the table, which shows the values of the equilibrium constants at different temperatures

Task: T10 1027 C, CT1 30, T20 1157 C, CT2 15

When solving this task, you must first explain the meaning and meaning of the equation of the isobar of a chemical reaction. When answering the question, do not forget to indicate which process (exothermic or endothermic) corresponds to the value of the thermal effect you obtained.
