WebExpert Answer. Transcribed image text: 2. The adiabatic exothermic irreversible gas-phase reaction 2 A+B 2C is to be carried out in a flow reactor for an equimolar feed of A and B. A Levenspiel plot for this reaction is shown below. a. The basic principle underlying this technique is that when the sample undergoes a physical transformation such as phase transitions, more or less heat will need to flow to it than the reference to maintain both at the same temperature. Whether less or more heat must flow to the sample depends on whether the process is exothermic or endothermic. For example, as a solid sample melts to a liquid, it will require more heat flowing to the sample to increase its temperatur… WebExothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases.
