According to collision theory for determining the variation of rate of reaction with temperature the rate constant,`k= Ae^(-Ea//RT).` For most of the practical purposes A and `E_(a`[Arrhenius factor and Activation energy] are temperature independent. However they may vary slightly. Assuming the conditions given above answer the following questions. For constant A and `E_(a),` which parameters when plotted will give a straight line with given slope?A. `"ln k vs T ,Slope" = (E_(a))/(R)`B. `"ln k vs" 1/T "slope" = (E_(a))/(R)`C. `"ln k vs"1/T,"slope"=(E_(a))/(R)`D. `"ln k vs" T,"slope"=(E_(a))/(R)`
If an element can exist in several oxidation states, it is convenient to display the reduction potentials corresponding to the various half reactions in diagrammatic from, known as Latimer diagram.

The standard potentials for two nonadjacent species can also be calculated by using the concept that `DeltaG^(@)` is an additive property but using potential is not an assitive property and `DeltaG^(@)=-nFx^(0),` If a given oxidation state is a the next higher oxidation state disproportionation can occur. The reverse of relative stabilities of the oxidation state can also be understood by drawing a graph of `DeltaG^(@)//F` against oxidation state, known as Frost diagram, Choosing the stability of zero oxidation state arbitrery as zero.
