Question

In the reaction, \[\ce{N2 + 3H2 -> 2NH3}\], the rate of disappearance of H₂ is 0.02 Mis. The rate of appearance of NH₃ is ______.

विकल्प

• 0.0133 M/s

• 0.004 M/s

• 0.032 M/s

• 0.023 M/s

Answer 1

In the reaction, \[\ce{N2 + 3H2 -> 2NH3}\], the rate of disappearance of H₂ is 0.02 Mis. The rate of appearance of NH₃ is 0.0133 M/s.

Explanation:

\[\ce{N2 + 3H2 -> 2NH3}\]

Rate of reaction = `- ("d"("N"_2))/"dt" = - 1/3 ("d"("H"_2))/"dt" = 1/2 ("d"("NH"_3))/"dt"`

From rate expression,

`("d"("NH"_3))/"dt" = 2/3 ("d"("H"_2))/"dt"`

`= 2/3 xx 0.02` = 0.0133 M/s
