taon pure 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 night.) The temperature of the water bath is monitored, and it is determined from this data that 140. J 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 piston does 377. W of work on the system during the reaction worth is the reaction thermie or endothermic? exothermie endotherm up down X Does the temperature of the water both go up of reither in out Does the piston move in or out release Does the reaction absorberenergy How much energy does the reaction sharbor release Be sure your answer has the correct er significant dit OM
