Everything else being equal, write a general expression to show how the exchange current density for a reaction changes as a function of temperature. In other words, write an expression for j0(T) at an arbitrary temperature T as a function of j0(T0) at a reference temperature T0. If a reaction has j0 = 10-8 A/cm2 at 300K and j0 = 10-4 A/cm2 at 600K, what is ∆G1 + + for the reaction? Assume that the T0 is 300K.
