Furthermore, Chapter 9 solutions introduce the concept of versus first-law efficiency. A student might calculate that an Otto cycle is 60% efficient (first law), only to find that its second-law efficiency is 85%—meaning it is doing remarkably well compared to a reversible engine. This reframes failure. A low first-law efficiency might not be a design flaw; it might be a physical limit imposed by the Carnot cycle. The solution teaches the engineer to distinguish between what is possible and what is merely plausible.
