Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion
Efficiency of a reversible heat engine will be highest at -273°C temperature of cold reservoir.
Reason
The efficiency of Carnot’s engine depends not only on the temperature of cold reservoir but also on the temperature of hot reservoir and is given by η = 1 - T₂/T₁.
