Title: Determination of Activation Energy for the Reaction of Bromide and Bromate Ions in Acid Solution. Objective: –

Determine the time taken for the phenol to be reacted completely with bromine at certain temperature.

–

Determine the activation energy for the reaction by plotting the graph of logarithm of time taken against the reciprocal of absolute temperature.
