Topic 6 Kinetics 


6.1 Rate of reaction 

Understandings:
The rate of reaction is expressed as the change in concentration of a particular reactant/product  per unit time.
Guidance:
Calculation of reaction rates from tangents of graphs of concentration, volume or mass vs time should be covered.

Rate of reaction worksheet


6.1 Experiments that measure rate of reaction 
Understandings:
Concentration changes in a reaction can be followed indirectly by monitoring changes in mass, volume and colour.



6.1 Analysing rate of reaction graphs
Applications and skills:
Analysis of graphical and numerical data from rate experiments.

6.1 Temperature and kinetic energy 
Applications and skills:
Description of the kinetic theory in terms of the movement of particles whose average kinetic energy is proportional to temperature in Kelvin.


6.1 Collision theory 
Understandings:
Species react as a result of collisions of sufficient energy and proper orientation.






6.1 Activation energy 
Understandings:
Activation energy (Ea) is the minimum energy that colliding molecules need in order to have successful collisions leading to a reaction.


Collision theory and activation energy worksheet

6.1 Factors that affect the rate of a chemical reaction 
Applications and skills:
Explanation of the effects of temperature, pressure/concentration and particle size on rate of reaction.
Construction of Maxwell–Boltzmann energy distribution curves to account for the probability of successful collisions and factors affecting these, including the effect of a catalyst (catalysts are covered in the next video). 


​Factors that affect the rate of reaction worksheet

6.1 The effect of catalysts on the rate of a reaction 
Understandings: 
By decreasing Ea, a catalyst increases the rate of a chemical reaction, without itself being permanently chemically changed.

Applications and skills:
Construction of Maxwell–Boltzmann energy distribution curves to account for the probability of successful collisions and factors affecting these, including the effect of a catalyst.
Sketching and explanation of energy profiles with and without catalysts
