Explain the phase rule for reacting and non -reacting systems and determine the number of degrees of freedom.
00:10
The phase rule is a principle that our number of degrees of freedom is equal to our number of components minus our number of phases plus two.
00:22
In non -reacting systems, the components don't undergo any chemical changes.
00:31
So the phase rule applies as shown.
00:36
As above.
00:40
Now for reacting systems, the phase rule is modified.
00:44
So now we have f is equal to c minus p plus two minus r our number of independent reactions.
00:53
So it is modified slightly.
00:56
Next we like to find our number of degrees of freedom.
01:00
So let's first identify our components.
01:03
We have co, co2, h2, h2, h2, and ch4...
