WebFor the reaction to occur in a voltaic (galvanic) cell, ∆G > 0. False Oxidation occurs at the cathode of a galvanic cell, but at the anode of an electrolytic cell. False A salt bridge provides a path for the electrons to move between the anode and cathode compartments of a voltaic cell. False WebGalvanic (or voltaic) cells use a thermodynamically favored redox reaction to generate an electric current. Each half-reaction takes place in a separate compartment, or half-cell, containing an electrode. The electrode where oxidation occurs is the anode, and the electrode where reduction occurs is the cathode. how fast is a peregrine falcon dive https://gcprop.net
