A mixtu 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. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 117. kJ 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 piston does 223. kJ of work on the system during the reaction. exothermic Is the reaction exothermic or endothermic? O endothermic O up O down x 5 ? Does the temperature of the water bath go up or down? O neither in Does the piston move in or out? O out O neither absorb Does the reaction absorb or release energy? O release O neither How much energy does the reaction absorb or release? Be sure your answer has the correct number of significant digits.
