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

  1. A8 ~mm ~min ⁻¹
  2. B2 ~mm ~min ⁻¹
  3. C16 ~mm ~min ⁻¹
  4. 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
