The reaction 2no 2(g) → 2no(g) + o 2(g) is suspected to be second order in no 2. which of the following kinetic plots would be the most useful to confirm whether or not the reaction is second order? a plot of [no2]−1 vs. t a plot of ln [no2] vs. t a plot of [no2] vs. t a plot of ln [no2]−1 vs. t a plot of [no2]2 vs. t

A plot of [NO₂]⁻¹ vs t

Explanation:

If the reaction:

2NO₂(g) → 2NO(g) + O₂(g)

follows the second order reaction:

-Δ[NO₂] / Δt = k [NO₂]²

-Δ[NO₂] / [NO₂]² = kΔt

-∫ Δ[NO₂] / [NO₂]² = ∫ kΔt

[NO₂]⁻¹ + c = kt + c

[NO₂]⁻¹ = kt + c

Thus, a plot of [NO₂]⁻¹ vs t will have as slope the rate constant and proves the reaction follows the second order reaction.

I hope it helps!

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
