Question

For which of the following represents the expression for three/forth life of reaction? (A) (k/2.303) log 4 / 3 (B) (2.303/k) log 3 / 4 (C) (2.303/k) log 4 (D) (2.303/k) log 3

Tardigrade Admin · Accepted Answer

t3 / 4=(2.303/k) log (1/(1-(3)4))=(2.303/k) log 4

Q. For which of the following represents the expression for three/forth life of reaction?

$\frac{k}{2.303} lo g 4/3$

$\frac{2.303}{k} lo g 3/4$

$\frac{2.303}{k} lo g 4$

$\frac{2.303}{k} lo g 3$

$t_{3/4} = \frac{2.303}{k} lo g \frac{1}{( 1 - \frac{3}{4} )} = \frac{2.303}{k} lo g 4$

2.303k​log4/3

k2.303​log3/4

k2.303​log4

k2.303​log3

t3/4​=k2.303​log(1−43​)1​=k2.303​log4

$\frac{k}{2.303} lo g 4/3$

$\frac{2.303}{k} lo g 3/4$

$\frac{2.303}{k} lo g 4$

$\frac{2.303}{k} lo g 3$

$t_{3/4} = \frac{2.303}{k} lo g \frac{1}{( 1 - \frac{3}{4} )} = \frac{2.303}{k} lo g 4$
