Kinetics

Question 1

How do we determine reaction order?

Answer 1

By using experiments

Question 2

What are intermediates?

Answer 2

Products are canceled out as reactants

Question 3

What are catalysts?

Answer 3

Reactants are consumed first in the reaction and are canceled out as products

Question 4

Is the rate law dependent on products or reactants?

Answer 4

Reactants

Question 5

Reaction rate is studied under conditions where the reverse order does not contribute to the overall rate.
T/F

Answer 5

True

Question 6

Catalysts can lower the activation energy.
T/F

Answer 6

True

Question 7

What are the units for a second-order reaction?

Answer 7

mol^-1 ⋅ s^-1

Question 8

What are the units for a first-order reaction?

Answer 8

s^-1

Question 9

What are the units for a zero-order reaction?

Answer 9

mol / s

Question 10

An increase in temperature increases the reaction rate because

Answer 10

More collisions will have enough energy to exceed the activation energy, leading to a faster reaction.

Question 11

How can we determine the activation energy for the reverse reaction with the enthalpy of a reaction?

Answer 11

𝐸𝑎 (reverse) = 𝐸𝑎 (forward) − ΔH
