Question

to what extent do enzymes affect the energy of the reaction in the following: - more reactants choose your answer... the reaction speed - enzymes choose your answer... the activation energy - more products choose your answer... the reaction speed

Explanation:

1. For "more reactants" and "the reaction speed": Increasing the amount of reactants generally increases the frequency of effective collisions, so more reactants increase the reaction speed.
2. For "enzymes" and "the activation energy": Enzymes act as biological catalysts. Catalysts lower the activation energy of a reaction to make it proceed faster, so enzymes decrease the activation energy.
3. For "more products" and "the reaction speed": Having more products typically shifts the reaction equilibrium (Le Chatelier's principle) and slows down the forward reaction speed (as the reverse reaction may be favored or the concentration gradient for forward reaction is reduced), so more products decrease the reaction speed.

Answer:

• more reactants: increase the reaction speed
• enzymes: decrease the activation energy
• more products: decrease the reaction speed
