Rates of Reaction

Watch the video and take notes.

Rates of reaction: https://www.youtube.com/watch?v=4SK4IlQjZZ4

You must write clearly about the rates of reaction and factors affecting them. Make use of worksheets used previously in class if you get stuck.

A factor is something that affects the rate of the reaction (like in the graphs you have studied). Example: temperature

After finishing this complete the following worksheet:

Neutralization Reaction

Trends in Periodic Table

Write definitions of:

Atomic radius
Electron Affinity
Ionization Energy
Electronegativity


More electron affinity results in more ionization energy. So, it is more difficult to lose an electron or  separate an electron that is already in the atom.

Electronegativity increases across the period. The trend is opposite to that of the atomic radius.
