Rate Of Reaction Flashcards
1
Q
What is the average rate of a reaction
A
The total change in concentration of reactants/products divided by the time taken for the reaction to take place
2
Q
What is instantaneous rate
A
The rate of change occurring at a specific time in the reaction
3
Q
How to find instantaneous rate
A
Find gradient of tangent at point
4
Q
What must a property be to find the rate by dividing rate of change of property by time
A
Must be proportional to concentration as og equation was change in concen/time
5
Q
What is the rate of reaction
A
Measures the rate of formation of a product/ rate of removal of a reactant
6
Q
Two reasons why a reaction may get faster as it progresses
A
-if it is exothermic and the temperature rises
-if the reaction gives a product that can act as a catalyst for the reaction
