In the reaction : 2N₂O₅ → 4NO₂ + O₂, initial pressure is 500 atm and rate

In The Reaction 2no 4no O Initial Chemistry Question

In the reaction : 2N₂O₅ → 4NO₂ + O₂, initial pressure is 500 atm and rate constant k is 3.38 ˣ 10⁻⁵ s⁻¹.After 10 minutes the final pressure of N₂O₅ is

Options

(a) 490 atm
(b) 250 atm
(c) 480 atm
(d) 420 atm

Correct Answer:

490 atm

Explanation:

P₀ = 500 atm. k = 2.303 / t log₁₀ p₀ / p(t), 3.38 ⨯ 10⁻⁵ = 2.303 / 10⨯60 log 500/ p(t) or, 0.00880 = log 500 / p(t) ⇒ 500 / 1.02 = 490 atm.
