    efficiency n=1 -(q1/q2) for a normal heat engine

    But how efficiency n=1 -(t1/t2) ? for reversible heat engine

    When using the temperatures, you find the theoretical highest efficiency possible for a specific system.

    When using the "Q" (heat), you find the actual efficiency of the system.
