We are being asked to calculate the internal energy in kilojoules (kJ) of the ideal gaseous reaction. The internal energy (ΔE or ΔU) of a system can be calculated from the heat and work of the system. The relationship between internal energy, heat, and work is shown in the following equation:
An ideal gaseous reaction (which is a hypothetical gaseous reaction that conforms to the laws governing gas behavior) occurs at constant pressure of 30.0 atm and releases 67.9 kJ of heat. Before the reaction, the volume of the system was 8.00 L. After the reaction, the volume of the system was 2.80 L.
Calculate the total internal energy change, ΔE, in kilo joules.
