What does a catalyst do in a chemical reaction?
Answer and explanation
Correct answer: A. It lowers the activation energy and is not consumed
- Step 1: A catalyst provides a different pathway with lower activation energy. Step 2. It speeds up both the forward and reverse reactions. Answer: it lowers the activation energy and is not consumed. Why not the others: Catalysts provide an alternative reaction pathway that lowers activation energy without changing overall thermodynamic equilibrium or being permanently consumed.
