SO_(3) gas is entering the environment at a constant rate of 6.93 xx 1

1.	SO_(3) gas is entering the environment at a constant rate of 6.93 xx 10^(–6) gm/L/day due to the emission of polluting gases from thermal power plant, but at the same time it is decomposing & following first order kinetics with half life of 100 days. Based on above information select the true statement(s).
Answer» Concentration of `SO_(3)` in Kota is `1.25 xx 10^(–5) M` (Assume `SO_(3)` present in air reaches STEADY state) If `10^(3)` L of air is passed through 1 L pure water (assuming all `SO_(3)` to be dissolved in it) & resulting solution is titrated against 1 N NaOH solution, 15 ml is required to reach end POINT. An INDUSTRY is manufacturing `H_(2)SO_(4)` at the rate of980 kgper DAY with the use of `SO_(3)` in air it should use `8 xx 10^(5)` Litre air /day. If `SO_(3)` emission is stopped then after 1000 days its concentrations will reduce to `~~ 1.2 xx10^(–8) M`. ANSWER :A::D
