Final answer:
When the activation energy is lowered in a chemical reaction, the products can combine more easily.
Step-by-step explanation:
True. Lowering the activation energy in a chemical reaction allows the reactant molecules to possess enough energy to overcome the energy barrier and form products more easily. This can be achieved by adding a catalyst, which provides an alternative pathway with a lower activation energy. For example, the catalytic converter in cars lowers the activation energy of harmful reactions in exhaust gases, allowing them to convert into less harmful substances.
