First order reaction is found to have rate constant, `k= 5.5xx 10^(-14) s^-1`. Find the half life to the reaction.

Text Solution

Verified by Experts

`K = 5.5 xx 10 ^(-14) sec ^(-1)`
`t _(1//2) = ( 0. 693)/(k) implies t _(1//2) = ( 0. 693)/( 5.5 xx 10 ^(-14)) = 0. 126 xx 10 ^(14)`
`t _(1//2) = 12.6 xx 10 ^(12) sec.`
