Some thermodynamics of photochemical systems
WebNov 12, 2024 · "3-D photochemistry plays a huge role because it provides heating or cooling, which can affect the thermodynamics and perhaps the atmospheric composition of a planetary system," Chen said. WebSolution. In photochemical changes, hν is included and hν is not thermal energy, so thermodynamic conditions do not apply. We cannot predict the probability of being in an electronic excited state from equilibrium thermodynamics. The main reason of excitation is not a result of thermal energy transfer, but rather the absorption of photon ...
