Q. |
Which of the following is the formula for condense phase rule? |
A. | f=c-p+2 |
B. | f=c-p+1 |
C. | f=c+p-2 |
D. | f=c+p-1 |
Answer» B. f=c-p+1 | |
Explanation: in a condensed phase rule system, the phases are represented in three dimension which is not suitable for graphic purposes and hence the pressure is considered to be zero (this is helpful in drawing 2d images). hence the formula reduces to f=c- p+2. |
