NEET Chemistry Chemical Kinetics Questions Solved


In a catalytic reaction involving the formation of ammonia by Haber's process N2+3H2 → 2NH3, the rate of appearance of NH3 was measured as 2.5 x 10-4 mol L-1S-1 The rate of disappearance of H2 will be

1. 2.5 x 10-4 mol L-1S-1

2. 1.25 x 10-4 mol L-1S-1

3. 3.75 x 10-4 mol L-1S-1

4. 15.00 x 10-4 mol L-1S-1

(3) N2+3H2 → 2N3

     -1/3dH2/dt = -1/2dNH2/dt

     -dH2/dt = 1/2x3x2.5x10-4

     -dH2/dt = 3.75 x 10-4 mol L-1S-1
