Question 1

What is the best definition of activation energy?

Group of answer choices

The energy required to end a chemical reaction

The energy required to form the bonds in the productmolecules

The energy required to break the bonds of the reactantmolecules

The energy required to bind a substrate to an active site

QUESTION 2

Which statement best describes how a catalyst can speed up achemical reaction?

Group of answer choices

A catalyst binds to enzymes to release substrates

A catalyst increases the concentration of reactants

A catalyst makes lower energy pathways available

A catalyst increases the concentration of products

QUESTION 3

If the activation energy required for a chemical reaction werereduced, what would happen to the rate of the reaction?

Group of answer choices

The rate would go up and down

The rate would decrease

The rate would increase

The rate would stay the same

QUESTION 4

How does a catalyst work?

Group of answer choices

By increasing the temperature of a reaction

By increasing the concentration of the reactants in areaction

By decreasing the pressure of the reaction

By decreasing the activation energy of a reaction

Question 5

Which component is affected when a catalyst is added to areaction?

Group of answer choices

The amount of products formed

The activation energy

The reaction energy

The concentration of reactants

Question 6

Explain why only asmall amount of catalyst is required to have a large impact on therate of a reaction. What happens during a catalyzed reactionthat makes it so no additional catalyst needs to be added duringthe reaction process no matter how large the amounts are ofreactants?
