A gaseous reaction $X_{2} (g) ⟶ Y + \frac{1}{2} Z (g)$ There is increase in pressure from $100 mm$ to 120 $mm$ in 5 minutes. The rate of disappearance of $X_{2}$ is

Options:

Answer:

Solution:

The increase in pressure shows the increase in conc. of $Z$ . Rate of appearance of $Z =$ $\frac{120 - 100}{5} = 4 mm min^{- 1}$ Rate of disappearance of $X_{2} = 2 \times$ rate of appearance of $Z$ $= 2 \times 4 mm min^{- 1} = 8 mm min^{- 1}$
