In the rankine cycle, as condenser pressure rises, thermodynamic efficiency. i. rises ii, falls iii. stays the same

False

Explanation:

We know that in Rankine cycle work is producing when steam is expanding through turbine.

From T-s diagram of Rankine cycle we can say that when condenser pressure is low then work will produce more because 80 to 90% work produces when steam will enter in the wet region.And when we will reduces the condenser pressure then work production will be less.

And we know that thermal efficiency is the ratio of net work out put to the heat supplied .So we can say that when we will reduce the condenser Pressure then efficiency will fall.
