WebAnother way to balance redox reactions is by the half-reaction method. This technique involves breaking an equation into its two separate components - the oxidation reaction and the reduction reaction. Since neither oxidation nor reduction can actually occur without the other, we refer to the separate equations as half-reactions. WebAug 20, 2024 · The transition from S α to S β can be described by the thermodynamic cycle shown in part (b) in Figure 19.3. 3, in which liquid sulfur is an intermediate. The change in entropy that accompanies the conversion of liquid sulfur to S β (−ΔS fus(β) = ΔS 3 in the cycle) cannot be measured directly. Because entropy is a state function ...
