Explanation / Answer

4)

The Balanced equation is:

N2 + 3H2 —> 2 NH3

rate of reaction can be written as:

rate of reaction = - rate of reaction of N2 = (-1/3)*rate of reaction of H2 = (1/2)*rate of reaction of NH3

a)

Use:

(-1/3)*rate of reaction of H2 = (1/2)*rate of reaction of NH3

rate of reaction of NH3 = (-2/3)*rate of reaction of H2

= (-2/3)*(-0.0860 M/s)

= 0.0573 M/s

Answer: 0.0573 M/s

b)

Use:

- rate of reaction of N2 = (-1/3)*rate of reaction of H2

rate of reaction of N2 = (1/3)*rate of reaction of H2

= (1/3)*(-0.0860 M/s)

= - 0.0287 M/s

Answer: - 0.0287 M/s
