If the average rate of appearance of nh3 in the following reaction is 1.40 m/s, what is the average rate of disappearance of h2 during the same time period?

n2(g) + 3h2(g) → 2nh3(g)

a. 5.40 m/s
b. 2.80 m/s
c. 1.20 m/s
d. 0.700 m/s
e. 2.10 m/s

E. 2.10 M/s

Explanation:

Let's consider the following balanced equation.

N₂(g) + 3 H₂(g) → 2 NH₃(g)

The molar ratio of NH₃ to H₂ is 2:3, that is, when 2 moles of NH₃ appear, 3 moles of H₂ disappear.

The average rate of appearance of NH₃ is 1.40 M/s. The average rate of disappearance of H₂ during the same time period is:
