SO₃ gas is entering the environment at a constant rate of 6.93 x 10^-6 g / L / day due to emission of polluting gases from thermal power plant at Kota but at the same time it is decomposing and following first-order kinetics with half-life of 100 days. Based on these details, select the correct statement(s) from the following.

Concentration of SO₃ in Kota is 1.25 x10^-5M (assume SO₃ present in air reaches
steady state)

If SO₃ emission is stopped, then after 1000 days, its concentration will reduce to 1.22 x 10^-8M

An industry is manufacturing H₂SO₄ at the rate of 980 kg per day with the use of SO₃ in air and it should use 8 x10⁵ L air per day

If 10³L of air is passed through 1L pure water (assuming all SO₃ is dissolved in it) and the resulting solution is titrated against 1N NaOH solution, 15 ml of NaOH solution is required to reach the end point
