Amixture 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 1atm . the cylinder is also submerged in a large insulated water bath. from previous experiments, this chemical reaction is known to release 178.kj of energy. the temperature of the water bath is monitored, and it is determined from this data that 285.kj of heat flows out of the system during the reaction. is the reaction exothermic or endothermic? the temperature of the water bath go up or down? updownneitherdoes the piston move in or out? inoutneitherdoes the gas mixture do work, or is work done on it? does workwork is done on itneitherhow much work is done on (or by) the gas mixture? round your answer to 3 significant digits.
