Problem:
Consider a   molecular system   containing   X type molecules   
and Y   type   molecules. X and   Y can interconvert, and   each   has   two energy   levels   (given below). The population    in moles (n),   of each energy state for X and Y, are given at    equilibrium   of   T=300K.

For X n₀=.8 and E=0
and n₁=.2 and E=?

For Y n₀=.6 and E=0
and n₁=.4 and E=?

What is the molar change in energy for total conversion from a completely populated X state to a completely populated Y state?

I honestly have no clue whatsoever for this. This is a Physics class and I don't know if this is supposed to be Chem review or what. I mean I don't even really understand what it means by interconvert. Is that suppose to be X+Y=XY or are we talking X+Y=more Y? But even understanding that I have no idea where to start.

Thanks for any assistance
