Initial concentration of reaction for nth order reaction is 'a' . Which of the following relations is correct about t_(1//2) of the reaction ?

Answer»

`LN t_(1//2)=ln("constant")-(n-1)log_(e)a`
`ln t_(1//2)=ln("constant")-ln a`
`t_(1//2)ln n=ln("constant")+ln a_(0)`
`ln t_(1//2)=nln a_(0)`

SOLUTION :`t_(1//2) prop (1)/(a^(n-1))`
`t_(1//2)-k(1)/(a^(n-1))`
`ln t_(1//2)=ln k -(n-1) log_(e)a`.
