2. Power plants that burn fossil fuels emit "flue-gas". The gas is at 6 MPa pressure in the power plant turbine, and then expands into the smokestack to 1 bar (100.0 kPa) as it is released to the atmosphere. The amount of energy the plant generates is 50 MJ per 1 m³ of gas that comes out of the smokestack and note that a typical power plant produces 1 GJ per second. a. Assuming that the flue-gas is at room temperature (25 °C) and behaves like a perfect gas, can you calculate n, Aq, Aw, and AU for the amount of gas that expands in the smokestack of a typical power plant in 1 second reversibly. b. And repeat the above irreversibly. You can still assume that the flue-gas behaves like a perfect gas.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

Transcribed Image Text:Question:
2. Power plants that burn fossil fuels emit "flue-gas". The gas is at 6 MPa pressure in the power
plant turbine, and then expands into the smokestack to 1 bar (100.0 kPa) as it is released to the
atmosphere. The amount of energy the plant generates is 50 MJ per 1 m³ of gas that comes out of
the smokestack and note that a typical power plant produces 1 GJ per second.
a. Assuming that the flue-gas is at room temperature (25 °C) and behaves like a perfect gas, can
you calculate n, Aq, Aw, and AU for the amount of gas that expands in the smokestack of a typical
power plant in 1 second reversibly.
b. And repeat the above irreversibly. You can still assume that the flue-gas behaves like a perfect
gas.
Hint: you know how much gas is released at the end of the process since you know T, P, and V.
