(I) There are several gases that are even stronger

I R

absorbers than

C O_{2} .

These are

C H_{4}, O_{3}, N_{2}

and

CFC .

Thus, these gases are responsible for greenhouse effect. Thus, given statement is false.
(II)

S O_{2} + O_{3} \to S O_{3} + O_{2} (T r u e)

(I) There are several gases that are even stronger IR absorbers than CO2​. These are CH4​,O3​,N2​ and CFC. Thus, these gases are responsible for greenhouse effect. Thus, given statement is false. (II) SO2​+O3​→SO3​+O2​(True)

(I) There are several gases that are even stronger $I R$ absorbers than $C O_{2} .$ These are $C H_{4}, O_{3}, N_{2}$ and $CFC .$ Thus, these gases are responsible for greenhouse effect. Thus, given statement is false.
(II) $S O_{2} + O_{3} \to S O_{3} + O_{2} (T r u e)$
