Q1. (a)A substance for which K is a constant undergoes  an  isothermal,  mechanically reversible process  from  initial  state  (P1,V1)  to  final  state  (P2,V2),  where V is  molar volume.

(i)Starting with the definition of K, show that the path of the process is described by:V=A(T)exp(-KP)

(ii)Determine an exact expression which gives the isothermal work done on 1 mol of this constant-Ksubstance

There is a solution on the webaite already but i cannot read the writing so please dont provide me with that one. thank you
