An engine is supposed to operate between two reservoirs at temperature `727^(@)C` and `227^(@)C`. The maximum possible efficiency of such an engine is

A

`1//2`

B

`1//4`

C

`3//4`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
A
`eta = (T_1-T_2)/(T_1) = ((273+727)-(273+227))/(273+727)`
`=(100-500)/(1000) = 1/2`.
