Kinetics

Question 1

Reactions can only occur under these requirements (3)

Answer 1

1. Sufficient energy (activation energy)
2. Two particles colliding
3. Collide in correct orientation

Question 2

Increase in temperature leads to what?

Answer 2

particles get more energy so more speed and => more frequent collisions => INCREASES RATE OF REACTION

Question 3

Increasing surface area increases what?

Answer 3

Increases chances of collisions + more exposure of reactants

Question 4

Increasing concentration leads to what?

Answer 4

More particles so => more frequent collisions => increased rate of reaction

Question 5

Increasing pressure does what?

Answer 5

Increases frequency of collisions => rate of reaction increases

Question 6

What do all the factors of rate of reaction (Pressure, Concentration, Temperature, and Surface area) all result in

Answer 6

More frequent successful collisions between reacting particles

Question 7

What does adding a catalyst do?

Answer 7

• Provide an alternative pathway with a lower activation energy
• Increase the rate of reaction while remaining chemically unchanged at the end of the reaction.

Question 8

In the distribution of a catalyst, what happens to the shape of graph in maxwell-boltzmann distribution?

Answer 8

Is the same but the activation energy is REDUCED. Meaning more molecules have energy greater than the activation energy.
