Answer 1

Answer #1

relative rate of reaction = 3.1 x 10^-3 M/s

average rate of NH₃ production = 6.2 x 10^-3 M/s

N₂concentration after 27 seconds = 1.17 M

Explanation

Rate of reaction = - $\Delta$ [N₂]/ $\Delta$ t = -(1/3)* $\Delta$ [H₂]/ $\Delta$ t = (1/2)* $\Delta$ [NH₃]/ $\Delta$ t

(1.) Rate of reaction = -(1/3)* $\Delta$ [H₂]/ $\Delta$ t

Rate of reaction = -(1/3) * ([H₂]_final - [H₂]_initial) / (t₂ - t₁)

Rate of reaction = -(1/3) * (0.25 M - 0.50 M) / (27s - 0)

Rate of reaction = 3.1 x 10^-3 M/s

(2.) Rate of reaction = (1/2)* $\Delta$ [NH₃]/ $\Delta$ t

$\Delta$ [NH₃]/ $\Delta$ t = (Rate of reaction) * 2

$\Delta$ [NH₃]/ $\Delta$ t = (3.1 x 10^-3 M/s) * 2

$\Delta$ [NH₃]/ $\Delta$ t = 6.2 x 10^-3 M/s
