Select one or more:
a. Chlorine forming a solid precipitate
b. Bubbles forming from hydrogen gas production
c. Solid zinc dissolving
d. Bubbles forming from chlorine gas production
Answer:
Increasing
Explanation:
(3) increases the reaction rate and has a higher activation energy
(4) increases the reaction rate and has a lower activation energy
Answer: Option (4) is the correct answer.
Explanation:
Activation energy is the minimum amount of energy required by the reactants to participate in the chemical reaction.
Therefore, reactant molecules whose energy is less than the activation energy are not able to participate in the reaction. Hence, a catalyst lowers the activation energy so that molecules with less energy can also participate in the reaction.
Thus, a catalyst is a specie that increases the reaction rate and has a lower activation energy.
