Question

For the reaction 3 H₂+N₂→ 2 NH₃, what is the rate of reaction when 0.068 moles of NH₃ at 7.4s then becomes 0.210 moles of NH₃ at 28.6 s ?

Answer 1

The rate of reaction is approximately 0.0067 moles/s.

Step-by-step explanation:

The rate of reaction can be determined by using the formula:

Rate of reaction = (change in concentration of NH₃) / (change in time)

Given that the concentration of NH₃ changes from 0.068 moles to 0.210 moles over a time interval of 28.6 s - 7.4 s = 21.2 s, we can substitute these values into the formula:

Rate of reaction = (0.210 moles - 0.068 moles) / 21.2 s

Rate of reaction = 0.142 moles / 21.2 s

Therefore, the rate of reaction is approximately 0.0067 moles/s.
