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 . the cylinder is also submerged in a large insulated water bath. (see sketch at right.) the temperature of the water bath is monitored, and it is determined from this data that of heat flows into the system during the reaction. the position of the piston is also monitored, and it is determined from this data that the system does of work on the piston during the reaction. is the reaction exothermic or endothermic? exothermic endothermic does the temperature of the water bath go up or down? up down neither does the piston move in or out? in out neither does the reaction absorb or release energy? absorb release neither

A chemical reaction involves the movement of energy to or from the environment. An exothermic reaction occurs when energy is transmitted to the environment, increasing the temperature.

Explanation:

1. The reaction is exothermic because energy is released as a result of it.

2. The released heat will be employed to operate on the piston and to raise the temperature due to the heat input from the eater bath, respectively.

As a result, the bath's temperature will rise.

3. As was already indicated, the heat generated will exert force on the piston, causing it to move out.

4. Energy produced during the reaction. Heat will therefore go from the gas combination to the bath.

The solution is hence "out."

5. We know the released energy = work + heat supplied to the bath

Given, energy = 390 kJ

work = 117 kJ

Clearly,

heat = energy - work

= (390 - 117) kJ

= 273 kJ
