This document is a complete summation of all the work covered in the chapter on rates and extents of chemical reactions. All the work that is specified on the SAGS document is covered in this document, including diagrams for further explanations. This document covers a wide range of topics includin...
,Rate of chemical reactions
The change in concentration per unit time of either a reactant or product
It can be explained as a measure of how
fast or slow a chemical reaction is
Units for reaction rate:
Cm3.s-1
g.s-1
Mol.s-1
Chemical reactions are effected by nature
of reacting substances, surface area of a
solid, concentration of a solution, pressure
of a gas, temperature and catalysts
, Measuring rates of reaction
1. Measuring the volume of gas produced over time
Graph analysis:
Start- reaction is
fastest
because [reactants
] is high.
Reaction slows
down as reactants
decrease.
End- reaction is
complete. No
reactants left
