For a binary mixture distillation process, the degree of freedom is 2. However, if the pressure is fixed in this process, the number of independent variables in this process will be ___________________?
Correct answer: A. 1
- A. 1
- B. 0
- C. 2
- D. 3
Explanation
A binary distillation system has two independent variables when pressure is allowed to vary. Fixing the pressure removes one degree of freedom, leaving one independent variable, commonly the composition or temperature.
