  • 1 answers

Rate of change of concentration ammonia = -0.2 * 10^-4 M/s

 

Explanation:

Given: N2+3H2 →2NH3. During the formation of ammonia 2 moles of nitrogen disappear in 1min. The volume of vessel is 1L.

Solution:

N2 + 3H2 -----> 2NH3

-d[H2] / dt = 0.3 * 10^-4 M/s

Rate = (1/3)(-d[H2] / dt)

        = (1/2) (d[NH3] /dt)

       = d[NH3] / dt

       = (2/3)( -d[h2]/dt)

       = d [NH3]/dt

d[NH3] /dt = -2/3 (0.3 * 10^-4)

 d[NH3] /dt = -0.2 * 10^-4 M/s

Rate of change of concentration ammonia is the answer.
