kinetics

Question 1

Collision theory

Answer 1

For a reaction to take place between two particles, they must collide with enough energy to break the bonds and also the collision must be between the parts of the molecule that are going to react together

Question 2

effect of Temperature increase

Answer 2

Increases the speed of the molecule, which increases both the speed of the molecules and the frequency of collisions

Question 3

effect of Concentration increase

Answer 3

Increases the frequency of collisions between the molecules, which increases the rate of the reaction

Question 4

effect of Pressure increase

Answer 4

Increases the frequency of collisions between the molecules, which increases the rate of the reaction

Question 5

effect of Surface area increase

Answer 5

Increases the rate of reaction because there are more sites for reaction

Question 6

Using a catalyst

Answer 6

Changes the rate of a reaction without chemically changing itself

Provide a different pathway for the reaction, one with a lower activation energy

Question 7

Activation energy

Answer 7

The minimum amount of energy the molecule must have for the reaction to start, the energy between the reactants and the transition state

Question 8

Maxwell-Boltzmann distribution

Answer 8

The distribution of energies of the molecules in a gas or liquid
