26 multiple choice 2 points what term describes the highest - energy structure in a molecular collision which leads to reaction? product reactant activation energy transition state
Answer
Answer:
D. transition state
Brief Explanation:
In a chemical reaction from reactants to products via molecular collisions, the transition - state is the highest - energy structure. Reactants have lower energy, products have lower energy than the transition state too, and activation energy is the energy barrier, not the structure itself.
