With what minimum pressure $\left(\text{in} \mathrm{kPa}\right)$ of a given volume of an ideal gas $\left({\mathrm{C}}_{\mathrm{p}.\mathrm{m}}=7/2\mathrm{R}\right)$, initially at $400$ $\mathrm{K}$ and $100$ $\mathrm{kPa}$ pressure, should be adiabatically compressed in order to raise its temperature to $600$ $\mathrm{K}$?

For a particular reaction $\mathrm{\Delta H}°=-76.6 \mathrm{KJ}$ and $\mathrm{\Delta S}°=226 {\mathrm{JK}}^{-1}.$ This reaction is

Look at the following diagram:

The enthalpy change for the reaction $\mathrm{A}\to \mathrm{B}$ will be
