A sealed, rigid, adiabatic vessel contains an ideal gas undergoing the exothermic first-order reaction A→B with ΔHr=−50,000 J/mol\Delta H_r = -50{,}000\ \text{J/mol}, initial concentration CA0=2.0 mol/LC_{A0} = 2.0\ \text{mol/L}, constant heat capacity Cv=25 J/(molK) and initial temperature T0=300 K. Assuming constant volume and that total moles remain unchanged, derive the differential equation relating temperature T to conversion XX and determine the final temperature when the reaction reaches 80% conversion.
