A Mixture Of Gaseous Reactants Is Put Into A Cylinder Where A Chemical Reaction Turns Them Into Gaseous Products The C 1 (73 KiB) Viewed 36 times

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, necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is als 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 dat that 260. 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 system does 318. kJ of work on the piston 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? Be sure your answer has the correct number of significant digits. exothermic endothermic up O down neither O in out neither O absorb O release neither ☐ kJ x10 X
