1 litre flask containing NH3 at 2.0 atm at 200 K is connected by a narj-ow tube of negligible volume to another 800 mL flask containing HCl(g) at 8.0 atm at 200 K. The two gases react according to equation NH3 + HCl (g) NHXI 4 (S) AH = - 43 kJ/mol If .heat capacity of HCl(g) Cv is 20 J K 1 mol ', determine the heat produced
