Question

The time of decay for a chemical reaction is given by t = 4tl/2. The relation between the mean life (T) and time of decay (t) is given by (A)  t = 2T ln 2  (B)  t = 4T ln 2 (C) t = 2T4 ln2 (D) t = (I/T2) ln2

Tardigrade Admin · Accepted Answer

t1 / 2=(t/4) and t1 / 2=T ln 2 So, (t/4)=T ln 2 ; t=4 T ln 2

Q. The time of decay for a chemical reaction is given by $t = 4 t_{l /2.}$ The relation between the mean life $(T)$ and time of decay (t) is given by

$t = 2 T l n 2$

$t = 4 T l n 2$

$t = 2 T^{4} l n 2$

$t = \frac{I}{T ^{2}} l n 2$

$t_{1/2} = \frac{t}{4}$ and $t_{1/2} = T ln 2$
So, $\frac{t}{4} = T ln 2; t = 4 T ln 2$

Q. The time of decay for a chemical reaction is given by t=4tl/2.​ The relation between the mean life (T) and time of decay (t) is given by

t=2Tln2

t=4Tln2

t=2T4ln2

t=T2I​ln2
