Which of the following combination is not feasible to be in equilibrium :

a. 10,10,10. c. 10,5,17
b. 5,10,12 d. 5,12,13

also give explanation

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
