Can someone please answer this question in simple terms and not over complicated. i know nothing about the subject. If you want to make a strong battery, should you pair two metals with high electron affinities, low electron affinities, or a mix? Explain your answer. (4 points)

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.
