Calculate the number of components and degrees of freedom for the reaction
NH4Cl(s) ⇋ NH3 (g) + HCl(g) in a closed vessel.
Answers
Answer:
Phase is the region of a compound or a material which is uniform in terms of chemical properties and is physically distinct from other phases. A phase is also mechanically separable. The diagram representing existence of phases at different pressures and temperatures is called Phase diagram.
In a phase diagram, at a particular point degree of freedom is defined as the parameters required essentially describing a phase. A degree of freedom is a useful property which is independent from other variables. The formula to calculate degree of freedom is called phase rule and it is represented as follows;
Where, is degrees of freedom, is number of components and is number of phases.
The number of variables that can be adjusted at equilibrium is equal to degree of freedom.
Component is the chemically distinct constituent of a system. Number of components depends on total number of constituents and the number of chemical constraints . Thye number of components is as follows;
Independent chemical reactions acts as constraints on the composition of system and contribute to the value of
