AQA A-Level Chemistry (new spec) 1.5Kinetics questions and answers
What is the collision theory? - Reactions can only occur when collisions take place
between particles when they have sufficient energy
Define activation energy - The minimum energy needed for particles to collide to
start a reaction
What does the Maxwell Boltzmann distribution show? - The spread of energies
that molecules of a gas or liquid have at a particular temperature
Why should the energy distribution go through the origin on the graph? - There
are no molecules with no energy
What is the Emp? - Most probable energy
Where is the Emp line on the graph? - From the peak down to the X-Axis
What does the area under the curve represent? - The total number of particles
present

Kinetics questions and answers
Why should the energy distribution never meet the x-axis? - Because there is no
maximum energy for molecules
What is the label for the y-axis? - Number of molecules within a given energy
What is the label for the x-axis? - Energy
What happens to the particles when the temperature is increased? - More
particles will have energy greater than the activation energy
What does Ea stand for? - Activation energy
What happens to the peak of the Maxwell Boltzmann distribution when the
temperature is increased? - It moves to a higher energy with a lower height
What happens to the proportion of molecules exceeding the activation energy
when the temperature is increased? - The proportion of molecules increases
