This is a better equation I found. Sorry I should have taken a picture instead. What I did was to plug in 100 on "TH" variable and the -5 K on the "TC" variable. I got an efficiency bigger than 100%. Would that make it violate the 2nd law that states that a system cant have 100% efficiency?

I don't understand, can you calculate efficiency only using the temperature?

Since the system is doing no work, would it be just 4513 J? I don't think there is any other information to use
