Explain the relationship between color intensity and amount of reaction.

Which are important thermodynamic parameters associated with the completion of a single step reaction? Explain its energy profile diagram. Sketch diagrams for exo-and endothermic reactions?

Why is hydrogen peroxide an oxidizing agent? Explain the terms of “rate constant” and “rate equation” in an Iodine clock reaction. (Hint: relate your definition with respect to concentration).       Besides concentration, what are other factors that affect the rate of reaction? Explain.

Consider a reaction taking place in an aqueous solvent. The transition state for this reaction is capable of interacting more strongly with the aqueous solvent (through low potential energy interactions, including hydrogen-bonding) than with the reactant/ground state. Despite these strong potential energy interactions, the reaction rate is not significantly faster than the same reaction taking place in a non-polar solvent. Why? a)The transition enthalpy is unchanged by the aqueous solvent b)The transition Gibbs energy is reduced in the aqueous solvent c) The transition entropy is significantly negative in the aqueous solvated reaction d) The transition state internal energy is significantly negative in the aqueous solvated reaction d) none of the above
