How To Calculate Rate Of Reaction Flashcards
1
Q
What is the graph
A
Amount of product formed = Y
Time = X
2
Q
What does a steeper line indicate
A
Faster rate of reaction
3
Q
What happens to the line over time
A
It goes less steep; all the product gets used up
4
Q
What do the quickest reactions look like
A
- steep lines and then becoming flat in the least amount of time
5
Q
What is the equation
A
Rate of reaction = Amount of reactant used or amount of product formed (divided by) time
6
Q
How can you measure if something has reacted
A
- visual changes: if a solution goes clear, cloudy, gains/loses colour. How quickly it does it
- Change in mass: when gas is released, mass drops. Depending on how quickly it drops is how quick the reaction is
- Volume of gas given off: the more gas given off in a time interval, the faster
