L1. Rates of Reaction and Collision Theory

1. Rate of reaction & Collision Theory

Keywords: Rate of Reaction particles, collision theory, energy

ALL: define rate of reactions

MOST: describe the factors which affect the rate of a reaction

SOME: explain why these factors affect the rate of a reaction using scientific terminology
S: How fast? AfL- what does rate or reaction mean and how do we show this?

I: Questions on slide 4 to be answered whilst watching Ted video on slide 5 (answers on slide 6 & 7). Factors affecting rate

M:
A1: information- what happens in a chemical reaction. Collision theory. Word fill-slide 10

A2:Practical M1/M2 (slides14-16) HA and rhubarb and rates RSC (slide 17) LA

P: 5 sentences, 5 words, 1 word.



H/W states of matter sheet for L3- differentiated LA & HA
Must be done for lesson 3






Practical A3:
HA if doing M1/M2:
-marble chips
- dilute HCl
-conical flasks
-gas syringe
-clamp stands
-stopwatch
-sodium thiosulfate
-black cross
(waste bucket for thiosulfate- it will smell! Open windows)

LA: Rhubarb, potassium manganate (VII) solution made in H2SO4 (acidified)
White tile and knives or pre-cut rhubarb.

If investigating conc. to look at the RSC document
