Amixture of gaseous reactants is put in to a cylinder, where a chemical reaction turns them in to 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.
from previous experiments, this chemical reaction is known to release 244. kj of energy.
the temperature of the water bath is monitored, and it is determined from this data that 150. kj of heat flows out of the system during the reaction.
1) is the reaction exothermic or endothermic?
2) does the temperature of the water go up or down?
3) does the piston move in, out, or neither?
4) does the gas mixture do work, or is work done on it?
5) how much work is done on (or by) the gas mixture?
