JEE Main 29 June 2022, Shift 2, Chemistry Q72

Question 72 of 90 in this shift, Chemistry question 12 of 30, Section A.

Sulphur dioxide is one of the components of polluted air. SO2\mathrm{SO_2} is also a major contributor to acid rain. The correct and complete reaction to represent acid rain caused by SO2\mathrm{SO_2} is
  1. (1)2 SO2+O2→2 SO32\ \mathrm{SO_2} + \mathrm{O_2} \rightarrow 2\ \mathrm{SO_3}
  2. (2)SO2+O3→SO3+O2\mathrm{SO_2} + \mathrm{O_3} \rightarrow \mathrm{SO_3} + \mathrm{O_2}
  3. (3)SO2+H2O2→H2SO4\mathrm{SO_2} + \mathrm{H_2O_2} \rightarrow \mathrm{H_2SO_4}
  4. (4)2 SO2+O2+2 H2O→2H2SO42\ \mathrm{SO_2} + \mathrm{O_2} + 2\ \mathrm{H_2O} \rightarrow 2\mathrm{H_2SO_4}Official answer
