A gaseous reaction X ₂( ~g ) Y + 1 2 Z ( g ) There is increase in pressure from 100 ~mm to 120 mm in 5 minutes. The rate of disappearance of X ₂ is
Options
- A8 ~mm ~min ⁻¹
- B2 ~mm ~min ⁻¹
- C16 ~mm ~min ⁻¹
- D4 ~mm ⁻¹
Correct answer
A. 8 ~mm ~min ⁻¹
Step-by-step solution
The increase in pressure shows the increase in conc. of Z . Rate of appearance of Z= 120-100 5 =4 ~mm ~min ⁻¹ Rate of disappearance of X ₂=2 rate of appearance of Z=2 4 ~mm ~min ⁻¹=8 ~mm ~min ⁻¹
