Thermodynamics deals with energy changes of macroscopic system.
a) Consider a chemical reaction taking place in a closed insulated vessel. To which type of thermodynamic system does it belong?
b) State the first law of thermodynamics.
c) 3 mol of an ideal gas at 1.5 atm and `25^oC` expands isothermally in a reversible manner to twice its original volume against an external pressure of 1 atm. Calculate the work done.
`[R = 8.314 JK^-1mol^-1]`
