4.6.1.1 RATES OF REACTION Flashcards
This topic appears in the exam every year so there's a high chance it will appear again this year. (6 cards)
How can the rate of a chemical reaction be found?
The rate of a chemical reaction can be found by measuring the
quantity of a reactant used or the quantity of product formed over
time
equations for mean rate of reaction
mean rate of reaction = quantity of reactant used
time taken
mean rate of reaction = quantity of product formed
time taken
what is the quantity of the reactant or product measured in?
The quantity of reactant or product can be measured by the mass in grams or by a volume in cm3.
what are the units of rate of reaction?
g/s or cm3/s or mol/s
on a graph for rate of reaction, what does a steeper line represent?
the steeper the line, the greater the rate of reaction
on a graph for rate of reaction, how can you determine how fast a reaction finishes?
when the curved line becomes a straight, horizontal line, that’s when you know the reaction has finished.
