A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The 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. 1 atm pressure piston cylinder From previous experiments, this chemical reaction is known to release 368. kJ of energy water bath gases The position of the piston is monitored, and it is determined from this data that the system does 125. kJ of work on the piston during the reaction exothermic 1. Is the reaction exothermic or endothermic?2. Does the temperature of the water bath go up or down? 3. Does the piston move in or out?4. Does heat flow into or out of the gas mixture?5. How much heat flows? Round your answer to 3 kJ significant digits
