JEE MAIN - Chemistry (2022 - 29th June Evening Shift - No. 7)
Sulphur dioxide is one of the components of polluted air. SO2 is also a major contributor to acid rain. The correct and complete reaction to represent acid rain caused by SO2 is :
2SO2 + O2 $$\to$$ 2SO3
SO2 + O3 $$\to$$ SO3 + O2
SO2 + H2O2 $$\to$$ H2SO4
2SO2 + O2 + 2H2O $$\to$$ 2H2SO4
Explanation
$$2\text{SO}_{2} +\text{O}_{2} +\text{2H}_{2} \text{O} \longrightarrow \text{2H}_{2} \text{SO}_{4} $$
Acid rain occurs due to increased concentration of oxides of sulphur and Nitrogen.
