M Common Ethical D. O THERMOCHEMISTRY Understanding the definitions of heat and work 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 133. kJ of energy. The position of the piston is monitored, and it is determined from this data that the piston does 116. kJ of work on the system during the reaction. O exothermic Is the reaction exothermic or endothermic?…
