The element Co exists in two oxidation states, Co(II) and Co(III), and the ions form many complexes. The rate at which one of the complexes of Co(III) was reduced by Fe(II) in water was measured. Determine the activation energy of the reaction, in kJ, from the following data: T (K) k (s−1) 293 0.054 298 0.100 Enter your answer in kilojoules per mole and use 3 sig figs.

The element Co exists in two oxidation states, Co(II) and Co(III), and the ions form many complexes. The rate at which one of the complexes of Co(III) was reduced by Fe(II) in water was measured. Determine the activation energy of the reaction, in kJ, from the following data:
T (K) k (s−1)
293 0.054
298 0.100
Enter your answer in kilojoules per mole and use 3 sig figs.
Expert Solution
Step 1
Activation energy - the minimum amount of energy that must be provided for compounds to result in any chemical reaction.
It is denoted by and the unit is Joules per moles (J/Mol) or kilojoules per moles (KJ/Mol) or kilocalories per moles
