Consider a chemical reaction taking place in a cylindrical vessel with a movable piston in a room at 25 0C and an atmospheric pressure of 1.75 atm. It is determined that the reaction transfers 32.146 kJ of heat to the surroundings and the total energy change of the system (ΔE) is -32.965 kJ.
Based on this information, determine what the final volume of the cylindrical vessel would be assuming the initial volume of the vessel was 2.50 L.
