The energy profiles for four different reactions are shown. Which reaction requires the least energetic collisions to reach the transition state?

Question

Quizplus · Accepted Answer

Reaction C requires the least energetic collisions to reach the transition state because it has the lowest activation energy. The lower the activation energy, the easier it is for the reactant molecules to overcome the energy barrier and reach the transition state. Reactions A, B, and D all have higher activation energies, indicating that they require more energetic collisions and are less likely to occur than reaction C.
