Batman (1989 film) short notice. Peters suggested Kim Basinger: she was able to join the production immediately and was cast. As a fan of Michael Gough's work in various Hammer Film Productions, Burton cast Gough as Bruce Wayne's butler, Alfred Pennyworth. Robert Wuhl was cast as reporter Alexander Knox. His character was originally supposed to die by the Joker's poison gas in the climax, but the filmmakers "liked [my] character so much," Wuhl said, "that they decided to let me live." Burton chose Billy Dee Williams as Harvey Dent because he wanted to include the villain Two-Face in a future film using the
Butler–Volmer equation the surface is equal to that in the bulk. There are two limiting cases of the Butler–Volmer equation: where formula_21 and formula_22 are constants (for a given reaction and temperature) and are called the Tafel equation constants. The theoretical values of the Tafel equation constants are different for the cathodic and anodic processes. However, the Tafel slope formula_22 can be defined as: where formula_25 is the faradaic current, expressed as formula_26, being formula_27 and formula_28 the cathodic and anodic partial currents, respectively. Butler–Volmer equation The Butler–Volmer equation (named after John Alfred Valentine Butler and Max Volmer), also known as Erdey-Grúz–Volmer
