The major reasons for more usage of molecular fluorescence spectrometry in comparison to molecular phosphorescence spectrometry should be discussed. Concept introduction: Phosphorescence spectrometry is closely related to fluorescence. The transition from excited to ground state takes time in this type of photoluminescence process.

Question

For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.
