If a catalyst were added to the reaction of crystal violet with sodium hydroxide, effects could occur is the mechanism of the reaction would change , the activation energy of the reaction would change and the rate of reaction would change.
When we add catalyst to the reaction the rate of reaction would change . the catalyst decreases the activation energy of the reaction . it will speed up the rate of the reaction. the mechanism of the reaction would change.
Thus, the catalyst lowers down the activation energy of the reaction . so, the rate of the reaction would change.
