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
