#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] |

#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 |
