Which of the following statements are correct?

Options

A. Time required for 75%
completion is 1.5 times of half life for zero order reaction.
B. Time needed for a definite fraction of 1st order reaction not vary with the initial concentration.
C. Time for 25% reaction is one third of half life in second order process
D. Rate of 1st order reaction gets doubled if the conc of the reactant in increased to a two fold value.

Answer

A, B, C, D

Explanation

`C_(0)-C_(t)=Kxxt,(C_(0)//2)/(C_(0)-C_(0)//4)=(Kxxt_(1/2))/(Kxxt)=t=3/2xxt_(1/2)(Kxxt_(1/2))/(Kxxt)=((1/(C_(0)//2)-1/(C_(0)))/((1/((3C_(0))/4))-1/(C_(0))))`,
`(t_(1/2))/t=1/(C_(0))xx(3C_(0))/(4-3)=(3C_(0))/(C_(0)xx1)=3,t=1/3xxt_(1/2)`
