WebMay 24, 2014 · Explanation: Exothermic and endothermic refer to changes in enthalpy ΔH. Exergonic and endergonic refer to changes in the Gibbs free energy ΔG. "Exo" and … WebDec 3, 2024 · This allows two chemicals to react and emit light in the form of chemiluminescence. Is the reaction exergonic or endergonic? Explain. Answer. Answer key [1, p. A-8]: The reaction is exergonic because it releases energy—in this case, in the form of light. (This is a nonbiological version of the bioluminescence seen in Figure 8.1.) …
question 1.17 - Columbia CTL
WebExergonic/endergonic has to do with the sign of ΔG, while exothermic/endothermic has to do with the sign of ΔH. Following the equation, a reaction can still be exergonic (-ΔG) and endothermic (+ΔH) if entropy is positive (+ΔS) and the temperature is high enough (to get a net negative result for ΔG). WebA strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system. journey concert setlist 2019 las vegas nv
