Consider the reversible and isothermal compression of 2.0 moles of ammonia (NH3 (g)) from an initial volume of 10.0 L to a final volume of 1.00 L, at a constant temperature of 298 K:
6a. Calculate the work w and heat q associated with this change in volume, considering NH3 to be an ideal gas.
6b. Calculate the work w (but not the heat) using the virial equation of state, with second virial coefficient B = −0.297 L/mol for NH3 at this temperature (and ignoring any higher coefficients).
A reversible and isothermal compression process is considered. In this process, the change in internal energy is zero.
So, heat q = -w (work done)
(a) For number of moles (n) = 2, initial volume (Vi) =10L, final volume (Vf) = 1L at temperature T = 298 K, work (w) and heat (q) involved can be calculated using gas constant (R), as,
