Explanation:
More effective catalyst would be the one with the lower activation energy, which means it is Cl.
<span>Collisions of the reagents must occur during the chemical reaction and a certain minimum energy called the activation energy is necessary for that reaction. Adding a catalyst has a function to increase the rate of a reaction by lowering that activation energy.</span>
The salt is a soluable substance so it dissolves with water and make a salt solution.
Your answer should be Chemical reaction
Answer:
