A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. Thie 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. The temperature of the water bath is monitored, and it is determined from this data that 181.kJ of heat flows out of the system during the reaction. a. Is the reaction exothermic or endothermic?
b. Does the temperature of the water bath go up or down?
c. Does the piston move in or out?
