What happens to the efficiency of a carnot engine if the temperature of the sink is lowered keeping that of source constant ?

A Carnot engine works between 1000 K and 250 K. It is required to increase the efficiency to 85% . By how much should the temperature (1) of the source alone be changed (2) sink alone be changed to get the desired result ?

What we call the P-T curve ,Where volume remains constant ?

t_1/4 can be taken as time taken for the concentration of the reactant to drop to 3/4 of the initial value. If the rate constant for a first order reaction is k, the t_ 1/4 can be written as :

For a zero order of reaction the t_(1/2) — concentration.

Which order of reaction obeys the relation t_(1//2)=1//ka :
