To calculate the degree of freedom of NH4Cl in this scenario, we need to take into consideration the number of independent variables and conditions that can be varied without affecting the other components.
In this case, NH4Cl decomposes into NH3 and HCl. When initially in an evacuated chamber, there are no other components present other than NH4Cl. The decomposition reaction is as follows:
NH4Cl(s) → NH3(g) + HCl(g)
Based on this chemical reaction, we can evaluate the degree of freedom by considering the number of components and the number of chemical equations involved.
In this case, we have three components: NH4Cl, NH3, and HCl.
First, we need to determine the number of chemical equations involved. Here, we have one equation: the decomposition reaction of NH4Cl.
Next, we plug the number of components (C) and the number of equations (E) into the equation:
Degree of Freedom (F) = C - E + 2
Degree of Freedom (F) = 3 - 1 + 2 = 4
Therefore, the degree of freedom of NH4Cl in this scenario is 4.
Please note that the degree of freedom represents the number of variables that can be independently changed without violating the constraints of the system.
