Assertion : Ozone in the troposphere is a product of ultraviolet radiations acting on dioxygen molecules.
Reason : Ozone is thermodynamically very stable.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the c orrect explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
d
Ozone is prsent in stratosphere , and is a product of ultraviolet radiations acting on `O_(2)`

Ozone is thermodynamically unstable and decomposes to molecular oxygen.
`O_(2(g))overset("UV")rarrO_((g))+O_((g))`
`O_((g))+O_(2(g))overset("UV")hArrO_(2(g))`
Ozone is thermodynamically unstable and decomposes to molecular oxygen.
`O_(3)overset(hv)rarr O_(2)+O+"Heat"`

The ozone at the higher levels of atmosphere is a product of UV radiations acting on____ molecule.

Explain why ozone is thermodynamically less stable then oxgen ?

Assertion: In the stratosphere, ozone is produced by the action of UV radiations on dioxygen. Reason: UV radiations split the molecules oxygen into free oxygen (O) atoms which combine with molecular oxygen to form ozone.

Assertion : Ozone layer in the upper region of atmosphere protects earth from UV radiations of sun. Reason : Ozone is a powerful oxidising agent as compared to oxygen.
