1. The problem statement, all variables and given/known data Calculate q, w, ∆E, and ∆H for the process in which 93.0 g of nitrous oxide gas (N2O) is cooled from 179°C to 55°C at a constant pressure of 4.00 atm. Cp(N2O) = 38.70 J K-1 mol-1 2. Relevant equations q= mCΔT ΔH=n(Cp)=n(qv)ΔT ΔE=q+w w= -pΔV *Probably something else too but I'm drawing a blank 3. The attempt at a solution q= (93.0g)(38.70 K-1Mol-1)(-124°C) → -446288.4 w= -(4 atm) (101.3) (?) = ??? *not 0 though* ΔE=-446288.4+w=??? ΔH= (2.113 moles)(-446288.4)(-124°C)= A really big and incorrect number Help?
