The question is incomplete, here is the complete question:

At a certain temperature this reaction follows second-order kinetics with a rate constant of 14.1 M⁻¹s⁻¹

Suppose a vessel contains SO₃ at a concentration of 1.44 M. 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.

The concentration of in the vessel after 0.240 seconds is 0.24 M

Explanation:

For the given chemical equation:

The integrated rate law equation for second order reaction follows:

where,

k = rate constant =

t = time taken= 0.240 second

[A] = concentration of substance after time 't' = ?

= Initial concentration = 1.44 M

Putting values in above equation, we get:

Hence, the concentration of in the vessel after 0.240 seconds is 0.24 M
