I'm having trouble with proving the following question. Can someone please help, please.(adsbygoogle = window.adsbygoogle || []).push({});

(1) Prove that if you had a heat engine whose efficiency was better than the ideal value (4.5) you could hook it up to an ordinary Carnot refrigerator to make a refrigeratior that requires no work input.

I know that efficency = 1-Qc/Qh and COP=1/(Qh/Qc - 1)but how do i prove the above question?
