1/29/2024 RATES WITH TEMPERATURE & ARRHENIUS EQUATION

Question 1

Generally, how does activation energy affect the rate of a reaction?

Answer 1

Generally, the greater the activation energy, the slower the reaction.

Question 2

How does temperature affect the rate constant for any reaction?

Answer 2

As temperature increases, the rate constant will increase (because concentration changes faster!).

Question 3

What is Collision Theory (of dating)? (What conditions facilitate a reaction??)

Answer 3

• Atoms/molecules MUST COLLIDE
• Atoms/molecules MUST BE PROPERLY ORIENTED
• Atoms/molecules MUST HAVE ENOUGH ENERGY

(single bond=dating)
(double bond=engaged)
(triple bond=marriage!)

Question 4

Why do exothermic reactions release energy?

Answer 4

Because the products are more stable than the reactants

(think of reaction pathway / activation energy graph)

Question 5

Are the products more or less stable than the reactants in endothermic reactions?

Answer 5

Products are less stable than the reactants in endothermic reactions

(think of reaction pathway / activation energy graph)
