SUMMARY
The discussion centers on a problem related to the Second Law of Thermodynamics, specifically involving a reversible engine operating between three thermal reservoirs: A, B, and C. The engine absorbs equal heat from reservoirs A and B at temperatures Ta and Tb, respectively, and rejects heat to reservoir C at temperature Tc. The efficiency of this engine is defined as α times the efficiency of a reversible engine operating between reservoirs A and C. The relationship Ta/Tb is established as (2α - 1) + 2(1 - α)Ta/Tc.
