Document Summary
The purpose of the experiment was to find the rate constant and the activation energy of reaction between a bidentate ligand, 1,10-phenanthroline and ferrous ions in an acidic solution which forms a iron (ii) cation. When 1,10-phenanthroline is present in acid, its dibasic property allows it to act as a base and it gets is protonated. Activation energy is the minimum energy that must be input to a chemical system, containing potential reactants, in order for a chemical reaction to occur. Part a determining the rate constant at 30 c. Optical density (1 min = 60 seconds) (at 510 nm) Figure 1: the above graph represents the relation between ln o. d and time where ln o. d is dependent on time. The slope of the graph represents the k in the following derivation which is essentially the rate constant of the reaction. The rate law for the overall reaction observed in this experiment can be written as.
