At a certain temperature the rate of this reaction is first order in SO₃ with a rate constant of 0.208 s⁻¹:
2SO₃(g) → 2SO₂(g) + O₂(g)
Suppose a vessel contains SO₃ at a concentration of 1.36M.
Calculate the concentration of SO₃ in the vessel 7.30 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits.

is the concentration at time t = ?![[A_0]](/tpl/images/0553/4332/9a686.png)
is the initial concentration = 1.36 M![[A_t]=1.36\times e^{-0.208\times 7.30}\ M=0.30\ M](/tpl/images/0553/4332/ec635.png)
