C because an ion either lost or gained an electron. Lithium is an alkali metal and a lithium ion usually has a +1 charge
<u>Answer:</u> Enzymes enhances the rate in the same order.
<u>Explanation:</u>
Catalyzed reactions are defined as the reactions in which a catalyst is used.
A catalyst is a substance which increases the rate of the reaction and does not participate in the reaction. It can be recovered at the end of the reaction. It decreases the activation energy of the reaction.
The rate of catalyzed reactions is always greater than the rate of uncatalyzed reactions.
Enzymes are the natural catalysts which are present in the animal body to increase the rate of some reactions.
Thus, they enhance the rate of both slow and fast uncatalyzed reaction at the same rate.
I believe the first option
Acting on the same object
The empirical formula represents the simplest whole number shows the simplest whole number ratio of atoms in a compound. An example of this is the empirical formula for glucose (C₆H₁₂O₆) is C₃H₆O₃.
I hope this helps. Let me know if anything is unclear.
