Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm. (Note: be careful what units you use, SI units needed) N2(g) + 3H2(g) → 2NH3(g)

From the information calculated above, can you tell the sign of the change in internal energy(ΔE)? If so, what is it and how can you tell? If not, what else you would need to know to be able to tell for sure? Explain clearly.
