A gaseous reaction X 2 ( g ) → Z ( g ) + 1 / 2 y ( g ) shows increase in pressure from 150 mm to 170 mm in 10 minutes. The rate of disappearance of X 2 is
Options
- A4 mm m i n - 1
- B16 mm m i n - 1
- C8 mm m i n - 1
- D2 mm m i n - 1
Correct answer
A. 4 mm m i n - 1
Step-by-step solution
Pressure α concentration Rate of appearance of y = 170 - 150 10 = 2 mm m i n - 1 Rate of disappearance of X 2 = 2 × rate of appearance of y = 2 × 2 = 4 mm m i n - 1 .
