1. [6 marks total] At 300 -C, ammonium chloride AH Sim decomposes according to Thermodynamic Data at 298 K (k.J mol-?) (J mol" K.1) NH CI(s) - NH;(g) + HCI(g) NH,CI (s) -314.4 94.6 Solid NH CI is sealed in an initially evacuated HCI(g) -92.3 186.9 cylinder at 300 C. After some time, the pressure NH,(g) -45.9 192.8 in the cylinder becomes constant. Determine this pressure, in bar
