Is the reaction exothermic or endothermic?
Does the temperature of the water bath go up or
down?
Does the piston move in or out?
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 right.)
From previous experiments, this chemical reaction is known to release 331. kJ of energy.
Does the gas mixture do work, or is work done
on it?
Explanation
The temperature of the water bath is monitored, and it is determined from this data that 223. kJ of heat flows out of the
system during the reaction.
How much work is done on (or by) the gas
mixture? Round your answer to 3 significant
digits.
