Acatalyzed reaction will have a activation energy, and this leads to a in the reaction rate. a) lower, decrease b) lower, increase eliminate c) higher, decrease d) higher, increase

B) lower, increase

Explanation:

he initial energy input is required to start a reaction is called activation energy. The activation energy lowers the energy required to chemical react happens. The activation energy is lowered by an enzyme which is called a biological catalyst. Thus, the enzyme lowers the activation energy and speeds up the rate of reaction. Reducing activation energy and speeds up the rate of reaction is called catalysis.
