#1 Posted 00:47am 09-02-10 aakash ft 1 The ratio of half life and two third life (t2/3) for a second order kinetics is 1. 3 : 4 2. 2 : 3 3. 3 : 2 4. 1 : 2 [hide] ans - 4 I want explanation[/hide]
But there is suffering in life, and there are defeats. No one can avoid them. But it's better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you're fighting for.

#2 Posted 09:44am 09-02-10 Re: aakash ft 1For a second order reaction, dA/dt = - k A[p]2[/p] This implies -dA/A[p]2[/p]=k dt Integrating, we get 1/A-1/A[ss]f[/ss]=k t 1/A-1/(A/2) = k t[ss]1/2[/ss] -1/A = k t[ss]1/2[/ss] so 1/A-1/(2A/3) = k t[ss]1/2[/ss] -1/2A = k t[ss]2/3[/ss] From which you get option 4

#3 Posted 0:54pm 09-02-10 Re: aakash ft 1" 1/A-1/(2A/3) = k t1/2 " ---> Sir here u mean t 2/3 ?? If yes then ya I got ur method THANKS
