N moles of a monoatomic gas is carried round the reversible rectangular cycle A B C D A as shown in the diagram. The temperature at A is T . The thermodynamic efficiency of the cycle is

Step-by-step solution

At A , temperature =T₀ , volume =V₀ , pressure -P₀ for n moles of monoatomic gas. At A, P₀ V₀=n R T₀ (cold) At B, 2 P₀ V₀=n R T_ high ^ T^ =2 T₀ Maximum thermal efficiency of the reversible engine of this Carnot's cycle = =1- T_C T_h =1- T₀ 2 T₀ = 1 2 =50 % .
