Problem 3- Clausius InequalityThe table below shows different processes occurring in a power cycle operating steadilybetween a hot and cold reservoirs at T₁ = 1800 K and T₁ = 600 K, respectively. Use the ClausiusInequality to evaluate and classify each case as reversible, possible, or impossible. Yourconclusion has to be based on the result of the evaluation of the inequality. Also, for each case,indicate if there is a violation of the first and/or second law of thermodynamics.Case Q₁ (kJ/s) Q₁ (kJ/s) Wnet (kW) Conclusion500100350500200250500150350500200300abCd
