Question

  1. A. Explain that barriers to reaction mean chemical reactions occur at different rates. is linked to key ideas in...
  2. B. An unrelated statement about Key ideas in chemistry
  3. C. A conclusion that ignores the evidence in the question
  4. D. A broader claim that goes beyond this specification point

Answer

Explain that barriers to reaction mean chemical reactions occur at different rates. is linked to key ideas in... is correct for this objective.

Explanation

Explain that barriers to reaction mean chemical reactions occur at different rates. is linked to key ideas in... is the supported choice because it connects directly to "Explain that barriers to reaction mean chemical reactions occur at different rates" and keeps the explanation inside the AQA GCSE Biology Key ideas in chemistry curriculum. The other options are weaker because they are either unrelated, unsupported by the objective, or too broad for this page.

Common mistake

Misunderstanding Reaction Rates

Students often think that barriers to reaction only affect the speed of the reaction and do not understand that they can prevent reactions from occurring altogether.

Emphasize that barriers to reaction can slow down or completely stop a reaction, and provide examples of how catalysts can lower these barriers to increase reaction rates.
