Weba) Equilibrium is achieved in a closed system when the rate of iron oxidation is equal to the rate of iron (III) oxide reduction. b) Because the process is spontaneous, the oxidation of iron must be fast. c) The energy of the universe is decreased when iron is oxidized to rust. d) The oxidation of iron is endothermic. WebElemental Reactions are triggered by applying certain combinations of elemental effects on a target (enemies, players, or objects). When an element is applied to a target, it will create an elemental aura that decays over time. Elemental Reactions will occur when a second element is applied onto a target with an existing elemental aura. Triggering elemental …

"In thermodynamics, a spontaneous process is a process which occurs without any external input to the system. A more technical definition is the time-evolution of a system in which it releases free energy and it moves to a lower, more thermodynamically stable energy state (closer to thermodynamic equilibrium). The sign convention for free energy change follows the general convention for thermodynamic measurements, in which a release of free energy from the syste… " - For a spontaneous electroreaction

Weba) A given enzyme catalyses just one type of reaction. b) While most enzymes are proteins, some are composed of RNA. c) The activity of enzymes is typically impaired at high temperatures. d) Enzymes act to lower the activation energy of a reaction by stabilising the transition state, but do not participate chemically in the reaction. WebApr 2, 2024 · A spontaneous pneumothorax is a collapsed lung. Part or all of the lung may collapse. Air collects in the pleural space (the space between the lungs and chest wall). The trapped air prevents your lung from filling, and the lung collapses. A spontaneous pneumothorax can happen in one or both lungs.
