A mixture of gaseous reactants is put into a cylinder, where a chemical reaction tums 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. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 300.J of heat flows out of the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the system does 316.kJ of work on the piston during the reaction. 1 atm pressure gases piston cylinder water bath Is the reaction exothermic or endothermic? exothermic endothermic 10 up Does the temperature of the water bath go up or down down? neither in Does the piston move in or out? Does the reaction absorb or release energy? How much energy does the reaction absorb or release? Round your answer to 3 significant dinits Ⓒout O neither absorb release O neither kJ n ?
