Question 1
Enzymes increase reaction rate by
◦ lowering the activation energy of a reaction.
◦ raising the activation energy of a reaction.
◦ converting an endergonic reaction to an exergonic reaction.
◦ increasing the free energy in the products.
Question 2
When a chemical reaction is in equilibrium,
◦ the reaction has stopped.
◦ there are equivalent amounts of substrates and products.
◦ the reaction is proceeding at its maximum rate.
◦ there is no net change in the amount of substrates or products.
