Answer:

\eta_{th} = 26.8\,\%

Explanation:

The maximum theoretical efficiency for a heat engine is given by the Carnot's Cycle. The temperatures of the hot reservoir and the cold reservoir at 1.0 atmosphere are 373.15 K and 273.15 K, respectively. Then:

\eta_{th} = \left(1 - \frac{T_{L}}{T_{H}}  \right)\times 100\,\%

\eta_{th} = \left(1-\frac{273.15\,K}{373.15\,K}  \right)\times 100\,\%

\eta_{th} = 26.8\,\%
