SUMMARY
The efficiency of a reversible heat engine can be determined from a P-V graph by analyzing the area enclosed by the process curves. In the discussed scenario, the P-V diagram features argon as the working substance, with specific points indicating isothermal processes at 423 K. The efficiency can be calculated using the formula for thermal efficiency, which is the ratio of work output to heat input, derived from the areas under the curves representing processes ab and ac.
