The reaction takes place at $T2$ temperature and $1$atm pressure. Substance K melts at Ti temperature and is TiKTz. Between $298K$ and Tz$,$ substance A is in the gaseous state, and substances & and L are in the gaseous state. Find it by drawing the energy diagram of the Kirchhoff Relation, which gives the reaction estalpy at $Tz$ temperature $($It will be assumed that all the necessary thermodynamic data are given for the calculations$).$
