The answers for these are 80%, 120 kJ, 30 kJ; 150 J/K, 150 J/K; and 0. I am a little confused about the topics

The accompanying diagram represents a reversible Carnot cycle for an ideal gas: Isotherm: T = 1000K Heat absorbed = 150 k.J Adiabatic D B Adiabatic Isotherm: T = 200 K V (a) What is the thermodynamic efficiency of the engine? (b) How much work is done by the gas? (c) How much heat is rejected at the lower temperature, 200 K, during the isothermal compression? (d) What is the entropy increase during the isothermal expansion at 1000 K? (e) What is the entropy decrease during the isothermal compression at 200 K? (f) What is the overall change in entropy for the entire cycle? [80%; 120 kJ; 30 kJ; 150 J K-'; 150 JK-'; 0]
