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. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 163. 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 118. kJ of work on the system during the reaction. Is the reaction exothermic or endothermic? Does the temperature of the water bath go up or down? 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 2 significant digits. exothermic O endothermic O up O down O neither in O out Oneither O absorb O release O neither x10 1 atm pressure gases piston cylinder water bath
