1. The second law of thermodynamics guesses the efficiency of a heat engine based on experience.
2. The second law of thermodynamics violates the definition of Carnot efficiency.
3. The competition between the second and first laws of thermodynamics in terms of thermal engine efficiency.
Please refer to the attached diagram for details
the first and second laws of thermodynamics both influence the hermal efficiency and performance of processes and systems. the first principle concerns the conservation of energy and its transformation into various forms. depending on the desired application, it is important to minimize the influence of related transformations leading to energy loss. the irreversibility of a step of a reversible process can lead to a characteristic energy loss influencing the overall yield of the reaction. friction, for example, degrades the efficiency and consequently the reversibility of a process. both principles have an influence but the first seems more influential because it requires complex technological arrangements to reduce loans while preserving optimal operation.
