8. Reaction kinetics

Question 1

term rate of reaction, frequency of collisions, effective collisions and non-effective collisions

Answer 1

rate of reaction-
frequency of collisions-
effective collisions-
non-effective collisions-

Question 2

effect of concentration and pressure
changes on the rate of a reaction

Answer 2

frequency of effective collisions

Question 3

define activation energy, EA

Answer 3

the minimum energy required for a collision to be effective

Question 4

effect of temperature change on the rate of a reaction

Answer 4

Boltzmann distribution and of frequency of effective collisions,

Question 4

Boltzmann distribution

Answer 4

significance of activation energy -

Question 5

catalyst

catalytic effect in terms of the Boltzmann distribution

Answer 5

reaction has a different mechanism, i.e. one of lower activation energy

activation energy line moves to left as more particles have energy greater than activation energy. no effect on shape of curve
