NEET Chemistry Chemical Kinetics Questions Solved


A gaseous reaction A2(g) → B(g) + 1/2C(g) show increase pressure from 100 mm to 120 mm in 5 minutes. The rate of disappearance of (A2) will be

1. 4 mm min-1

2. 8 mm min-1

3. 16 mm min-1

4. 2 mm min-1

(2) AZ(g) → B(g) + 1/2C(g)

     At t = 0               100             0           0

     At t = 5min      (100 - x)         x          x/2

     At t = 5min

          100+x/2  = 120

          x=40

          -dA2/dt = 40/5 = 8mm min-1
