31. However, abiotic redox reactions of arsenic are slow. 32. In redox reactions like this, there is an oxidizer and a fuel source to be oxidized. 33. Chini clusters can also be converted heterometal clusters and catalyze pH driven redox reactions and transport. 34. Cleavage is not a redox reaction and it has no consequence on the redox balance of fermentation. 35. In electrolysis, it should matter because the natural voltage between two nonspontaneous redox reactions should be negative. 36. The working mechanisms of pseudocapacitors are redox reactions , intercalation and electrosorption ( adsorption onto a surface ). 37. This faradaic energy storage with only fast redox reactions makes charging and discharging much faster than batteries. 38. The associated redox reaction , which is thermodynamically favorable in nature, is thermodynamic impossible under standard conditions. 39. Similarly, a redox reaction might occur in an battery can be recharged, driving the chemical reaction backwards. 40. Selenenic acids are believed to be transient intermediates in a number of redox reactions involving organoselenium compounds.
