Answer:
I3-(aq)
Explanation:
To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. This reaction may also be referred to as the iodine clock reaction. It yields the triodide ion which forms a blue complex with starch which enhances the determination of iodine even though iodine is coloured also.
Since the reaction is monitored by spectrophotometry, the concentration of the triodide ion can be monitored by spectrohotometric detection of the concentration of triodide ion present in the system. Hence we can use the determination of the amount of triodide ion by spectrophotometry to understudy this reaction.

Answer:
e) The activation energy of the reverse reaction is greater than that of the forward reaction.
Explanation:
- Activation energy is the minimum amount of energy that is required by the reactants to start a reaction.
- An exothermic reaction is a reaction that releases heat energy to the surrounding while an endothermic reactions is a reaction that absorbs heat from the surrounding.
- <em><u>In reversible reactions, when the forward reaction is exothermic it means the reverse reaction will be endothermic, therefore the reverse reaction will have a higher activation energy than the forward reaction.</u></em> The activation energy of the reverse reaction will be the sum of the enthalpy and the activation energy of the forward reaction.
