A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. 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.) piston cylinder The temperature of the water bath is monitored, and it is determined from this data that 181. 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 water bath system does 343. kJ of work on the piston during the reaction. gases olb Is the reaction exothermic or endothermic? exothermic endothermic O up Does the temperature of the water bath go up or O down X 5 ? down? neither O in Does the piston move in or out? O out neither absorb Does the reaction absorb or release energy? release neither How much energy does the reaction absorb or release? Be sure your answer has the correct K number of significant digits.
