Collision Theory
Reactions only occur when particles collide
1 of 15
Activation Energy
The minimum amount of energy required for particles to collide for a reaction to occur
2 of 15
Measuring Rate of Reaction - Mass Decrease
HCL and Calcium Carbonate - Measure mass before and after
3 of 15
Measuring Rate of Reaction - Gas
HCL and Calcium Carbonate - Measure mass of gas with a gas syringe
4 of 15
Measuring Rate of Reaction - Disappearing X
HCL and Sodium Thiosulfate - Measure time for cross to turn invisible
5 of 15
Gradient on Rate of Reaction Graph =
Rate of Reaction
6 of 15
Steeper Gradient =
Faster rate of reaction
7 of 15
Gradient =
dy / dx
8 of 15
What chemical is usually used as a catalyst
Transition Metals
9 of 15
Why can't catalysts be used forever
They are eventually poisoned despite not being used up
10 of 15
What does a catalyst do
Lower the activation energy of a reaction
11 of 15
Endothermic
Receives energy from its surroundings - Bond Breaking
12 of 15
Exothermic
Energy is given off - Bond Making
13 of 15
What is Dynamic Equilibrium
Substances move between states at an equal rate - no overall change
14 of 15
What is Le Chataliers Principal
If a change in conditions occurs to a closed reaction in equilibrium, a shift in equilibrium occurs to renew balance
