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 . The cylinder is also submerged in a large insulated water bath. (See sketch at right.) From previous experiments, this chemical reaction is known to release of energy. The position of the piston is monitored, and it is determined from this data "that the piston does of work on the system" during the reaction.
Required:
a. Is the reaction exothermic or endothermic?
b. Does the temperature of the water go up or down?
c. Does the piston move in, out, or neither?
d. Does The gas mixture do work, Or is work done on it?
e. How much work is done on (or by) the gas mixture?
