If a catalyst lowers the activation energy, what raises the activation energy?
•heat
•a reaction
•another catalyst
•an inhibitor

Answer

Explanation:

An inhibitor

Explanation: An inhibitor is a substance which lowers the rate of a chemical reaction by reducing the activity of a catalyst, enzyme etc.

An inhibitor increases the activation energy and therefore, reactant molecules which have low energy are not able to participate in the reaction. Therefore, formation of products will be slow.

Hence, we can conclude that if a catalyst lowers the activation energy, an inhibitor raises the activation energy.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
