For the reaction N 2 + 3 H 2 → 2 NH 3 The rate of change of concentration for hydrogen is 0.3 × 10 − 4 Ms − 1 The rate of change of concentration of ammonia is:
Options
- A− 0 .2 × 10 − 4 Ms − 1
- B0 .2 × 10 − 4 Ms − 1
- C0 .1 × 10 − 4 Ms − 1
- D0 .3 × 10 − 4 Ms − 1
Correct answer
B. 0 .2 × 10 − 4 Ms − 1
Step-by-step solution
N 2 + 3 H 2 → 2 NH 3 d H 2 dt = - 0 .3 × 10 - 4 Ms - 1 Rate = - 1 3 d H 2 dt = + 1 2 d NH 3 dt = d NH 3 dt = - 2 3 d H 2 dt = - 2 3 × ( - 0.3 × 10 - 4 ) = 0 .2 × 10 − 4 Ms − 1
