Question

3 - energy changes and rates of reactions (part 1)
question 9 (1 point)
which statement about catalysts is true?
catalysts change the equilibrium position
catalysts are consumed in the reaction
catalysts increase activation energy
catalysts provide an alternative pathway with lower activation energy

Explanation:

• Analyze each option:
• Option 1: Catalysts do not change the equilibrium position. They only speed up the rate at which equilibrium is reached. So this is false.
• Option 2: Catalysts are not consumed in the reaction. They remain chemically unchanged at the end of the reaction. So this is false.
• Option 3: Catalysts decrease the activation energy, not increase it. So this is false.
• Option 4: Catalysts work by providing an alternative reaction pathway that has a lower activation energy, which allows the reaction to occur faster. This is the correct description of how catalysts function.

Answer:

D. Catalysts provide an alternative pathway with lower activation energy
