3.1.9 Rate Equations Flashcards
(5 cards)
1
Q
definition of rate of reaction?
A
the usage of a reactant / the production of a product per unit time
2
Q
equation for rate of reaction?
A
change in concentration of the reactant or product/ mass
moldm-3s-1
3
Q
how to measure rate of reaction?
A
-initial rates method
-continuous monitoring method
4
Q
initial rates method?
A
-measuring time taken for reaction to reach recognisable stage of reaction
-then you can change one component of reaction and see how long it takes for the same stage to be reached
-produce a set of graphs and use tangent from 0 to calculate the initial rate on each one
y = products
5
Q
continuous monitoring method?
A
-follow a particular reaction from start to finish
-one graph from which you work out the rate of reaction at different points
y = reactants
