At a certain temperature this reaction follows second-order kinetics with a rate constant of 14.1 m⁻¹s⁻¹ : > 2so₃g + 2so₂g o₂g suppose a vessel contains so₃ at a concentration of 1.44m . calculate the concentration of so₃ in the vessel 0.240 seconds later. you may assume no other reaction is important. round your answer to 2 significant digits.

Answer : The concentration of SO₃ in the vessel 0.240 seconds later is, 0.24 M

Explanation :

The expression used for second order kinetics is:

where,

k = rate constant =

t = time = 0.240 s

= final concentration = ?

= initial concentration = 1.44 M

Now put all the given values in the above expression, we get:

Therefore, the concentration of SO₃ in the vessel 0.240 seconds later is, 0.24 M

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
