### Experimental DescriptionA mixture of gaseous reactants is contained in a cylinder where a chemical reaction converts them into gaseous products. The system is equipped with a piston that adjusts its position to maintain a constant pressure of 1 atm. The entire setup is submerged in a large insulated water bath for controlled conditions. The chemical reaction in the cylinder is exothermic, releasing 101 kJ of energy, as determined from prior experiments. During the reaction, the system performs 340 kJ of work on the piston.### Diagram ExplanationThe diagram illustrates a cylindrical setup with a piston at the top. The piston moves to maintain the pressure at 1 atm. Surrounding the cylinder is a water bath, which is insulated to prevent heat exchange with the environment. A thermometer indicates the water bath's temperature.### Questions and Options1. **Is the reaction exothermic or endothermic?** - [x] exothermic - [ ] endothermic2. **Does the temperature of the water bath go up or down?** - [ ] up - [x] down - [ ] neither3. **Does the piston move in or out?** - [ ] in - [x] out - [ ] neither4. **Does heat flow into or out of the gas mixture?** - [ ] in - [x] out - [ ] neither5. **How much heat flows? Round your answer to 3 significant digits.** \[ \text{Answer: } \_\_\_ \text{ kJ} \]The primary task is to calculate the heat flow associated with the described reaction and piston movement conditions.

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.) 1 atm pressure piston cylinder water bath From previous experiments, this chemical reaction is known to release 101. kJ of gases energy. The position of the piston is monitored, and it is determined from this data that the system does 340. kJ of work on the piston during the reaction. exothermic Is the reaction exothermic or endothermic? x10 endothermic up Does the temperature of the water bath go up or down? down neither in Does the piston move in or out? out neither O in Does heat flow into or out of the gas mixture? out neither How much heat flows?
