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.

The temperature of the water bath is monitored, and it is determined from this data that 300KJ of heat flows out of the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the piston does 316KJ of work on the system during the reaction.

a. Is the reaction exothermic or endothermic?

b. Does the temperature of the water bath go up or down?

c. Does the piston in or out?

d. Does the reaction absorb or release energy?

e. How much energy does the reaction absorb or release? Round your answer to 3 significant
