Question

11. [^]. A Carnot heat engine contains 8.00 moles of oxygen gas (assume Cr=2.5R). The
temperature of the heat source is 500.0 °C and the temperature of the cold reservoir is 25.0 °C.
Calculate the thermodynamic efficiency, V₁, V2, V3, V4, P3, P4, w and q for each step of the cycle
and the total heat and work of the cycle if P=20.0 bar and P₂ = 5.00 bar.

Expert Solution

Step 1

Thermodynamic efficiency of Carnot cycle, $η = \frac{T e m p e r a t u r e o f c o l d r e s e r v o i r}{T o f h o t r e s e r v o i r - T o f c o l d r e v e r v o i r} = \frac{298}{773 - 298} = 0.62 = 62 %$
