(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An ideal (Carnot) engine has an efficiency of 50 %

If it were possible to run it backward as a heat pump, what would be its coefficient of performance?

2. Relevant equations

COP = (T_{L}) / (T_{H}- T_{L})

3. The attempt at a solution

no temperatures are given. I just know that since e = 1 - T_{L}/ T_{H}then T_{L}/ T_{H}is 0.5 since the efficiency is 50%
