What is the main reason that it takes 2 to 3 minutes for the reaction to occur between sucrose and sulfuric acid in the dehydration of sucrose?

A reaction may take time to start because its reactants need enough energy to overcome the activation energy barrier. In the sucrose dehydration reaction, sulfuric acid acts as a dehydrating agent, but the reaction still needs this initial energy to proceed. Therefore, the correct choice is “The activation energy needs to be overcome in the reaction.”
