The 1 atm pressure cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 259. kJ of heat flows into the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the piston does 322. kJ of work on the system during the reaction. gases exothermic Is the reaction exothermic or endothermic? endothermic dn O…11 Syllabus_CHEM 1315 03-Gene XIm just a grade 6 student pls help me huhu.
