Question

A gaseous reaction X2(.g.) arrow Z(.g.)+1/2y(.g.) shows increase in pressure from 150 mm to 170 mm in 10 minutes. The rate of disappearance of X2 is (A) 4 mm min- 1 (B) 16 mm min- 1 (C) 8 mm min- 1 (D) 2 mm min- 1

Tardigrade Admin · Accepted Answer

Pressure α concentration Rate of appearance of y=(170 - 150/10)=2 mm min- 1 Rate of disappearance of X2=2× rate of appearance of y =2× 2=4 mm min- 1 .

Q. A gaseous reaction $X_{2} (g) \to Z (g) + 1/2 y (g)$ shows increase in pressure from 150 mm to 170 mm in 10 minutes. The rate of disappearance of $X_{2}$ is

$4 mm mi n^{- 1}$

$16 mm mi n^{- 1}$

$8 mm mi n^{- 1}$

$2 mm mi n^{- 1}$

Pressure $α$ concentration

Rate of appearance of $y = \frac{170 - 150}{10} = 2$ mm $mi n^{- 1}$

Rate of disappearance of $X_{2} = 2 \times$ rate of appearance of y

$= 2 \times 2 = 4$ mm $mi n^{- 1}$ .
