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.) From previous experiments, this chemical reaction is known to absorb 350. kJ of energy. The temperature of the water bath is monitored, and it is determined from this data that 295. kJ of heat flows into the system during the reaction. O exothermic Is the reaction exothermic or endothermic? O endothermic dn O Does the temperature of the water bath go up or down? имор о O' neither Does the piston move in or out? O neither O does work Does the gas mixture do work, or is work done on it? O work is done on it neither How much work is done on (or by) the gas mixture? Round your answer to 2 significant digits.
