Rate of formation `SO_(3)` in this reaction is `1.6xx10^(-3)kg//min`
`2SO_(2)+O_(2)to2SO_(3)` then rate at which ` SO_(2)` reacts is :-

Options

A. Assertion and reason both are correct and reason is correct explanation of assertion.
B. Assertion and reason both are wrong statements.
C. Assertion is correct but reason is wrong statement.
D. Assertion is wrong but reason is correct statement.

Answer

A

Explanation

Williamson.s synthesis occurs by `SN^(2)` mechanism and primary alkyl halides are most reactive in `S_(N)2` reactions.
