"7.2.2 I can deduce the extent of a reaction from the magnitude of Kc"

Blog Tasks

1. What does the word magnitude mean?
The size or amount
2. Explain why the three reactions above do not have units for Kc
The moles of the reactants equals the product so there is no units for K
Note: [units Kc]n
3. Deduce the extent of the reaction if Kc is
a. significantly larger than 1 – this means that there are more product produced compared the the reactants input. The (C+D) must be huge compared to (A+B). We can deduce that the reaction has taken place and almost go to completion
b. between 0.01 and 100- this means that there are There will be significant concentration of both the concentration and product. Normal reaction.
c. extremely – this means that there are less product produced compared to the reactants input. The (A+B) must be huge compared to (C+D). We can deduce that the reaction hardly proceeds.
