According to the mineralogical phase rule, the number of minerals that can coexist at equilibrium in a 8 component chemical system with 2 degrees of freedom is ..........
Show Hint
Correct Answer: 8
Solution and Explanation
Step 1: Use the phase rule equation.
The phase rule for a system with \( F \) degrees of freedom is given by: \[ F = C - P + 2 \]
Where:
- \( C = 8 \) (the number of components)
- \( P \) is the number of phases
- \( F = 2 \) (the degrees of freedom)
Rearranging the equation to solve for \( P \): \[ P = C + 2 - F = 8 + 2 - 2 = 8 \]
Thus, the number of minerals that can coexist at equilibrium in this system is 8.
