Rates of Reaction

?
Factors which alter rate of reaction
Concentration, pressure, temperature, surface area and catalysts
1 of 7
Catalyst
Increases the rate of reaction without being used up itself by providing an alternative reaction route with a lower activation energy
2 of 7
Homogeneous
In the same phase (state)
3 of 7
In a Boltzmann distribution, why must the curve start at the origin?
No molecules have no energy
4 of 7
What is significant about the area of the curve beyond the line marked Ea?
Only molecules in this area are able to react
5 of 7
How does increasing temperature affect the Boltzmann distribution?
The peak moves lower and to the right, with the same area under the curve
6 of 7
How to show the effect of a catalyst on a Boltzmann distribution
Draw a new line markes Ec to the left of the Ea line
