Question

The ean of persure: ( A_{2}(g) rightarrow B(g)+frac{1}{2} C(g) )
Initially exerearesme = I oo Afer reaction time peesuie ( 100-x quad x quad frac{1}{2} x ) Change in pressure ( 100+frac{1}{2} x=120 )
[
x=40 mathrm{mm}
]
"rate of disapperance of A ( _{2} ) u
( -frac{dleft[A_{2}right]}{d t}=frac{40}{5}=frac{8 m m}{m u}=8 mathrm{mm} min )
( (because d t=text { change in time }=5) )

# (4) atm/s2 (3) atm/s A gaseous reaction, 4. A3 (9) —>B(g) +--C(9) shows increase in pressure from 100 mm to 120 mm in 5 minutes. The rate of disappearance of A, is (1) 4 mm min-1 (2) 8 mm min-1 (3) 16 mm min-1 (4) 2 mm min-1 5. Which of the following will react at the highest rate?
