A heat engine is based on a gaseous cycle comprising of four processes viz. isothermal expansion at temperature `(T_(1))`, isochoric cooling to temperature `T_(2)`, isothermal compression (at `T_(2)`) and isochoric heating back to temperature `T_(1)`. The engine has been designed so as to completely use the heat rejected during isochoric cooling, in the isochoric heating process. Calculate the efficiency of this reversible cycle. Show the process on a PV graph.
