Answer to Question #89726 in Physical Chemistry for Sanyogita Kamble

Question

Application of phase rule in physical chemistry

Answer 1

Solution.

When we are dealing with a system, no matter how many components it contains, we must adhere to the rule of the Gibss phase. It can be written as an equation:

$$C = K+n-F$$

where K is the number of independent components, n is the number of factors determining the state, C is the number of external conditions that can be changed so that the number of phases remains constant, F is the number of phases in the system. This rule is used to understand that when certain conditions change, the system may change, for example, with a constant external pressure, temperature and concentration can be changed if the system is two-component (K = 2) and n = 2. This rule is also used in the rectification.
