Rates Of Reaction Flashcards
1
Q
What factors affect the rate of reaction
A
Higher the TEMPERATURE, quicker the ROR
Higher the CONCENTRATION , quicker the ROR
Larger the SURFACE AREA of reactant solid, quicker the rate of reaction
Higher the PRESSURE, quicker the ROR
2
Q
What do catalysts do
A
Speed up ROR
They’re not used up
3
Q
Rate of reaction equations
A
Rate= quantity of reactant used over time taken
Rate= quantity of product formed over time taken
4
Q
How to find slope of tangent
A
Y over X
5
Q
What does the steepness (gradient) of a graph show
A
Rate of reaction
6
Q
Collision theory
A
Chemical reactions occur when reacting particles collide with each other with sufficient energy.
7
Q
Activation energy
A
The minimum amount of energy colliding particles in a reaction need in order to react.
