Substituting the values in equation (5.13b), the free energy change takes the form
|
(5.14) |
Thus, this process is also favorable only when as in homogeneous nucleation.
From Fig. 57, we can write
|
(5.15) |
So from equation (98), we get
|
(5.16a) |
From Young’s equation, we know
|
(5.16b) |
The above equation is valid for the values of such that . If is the molar volume of liquid and is volume of liquid condensed on surface then, .
