Which of the following is correct - Vidyadip

MCQ

Which of the following is correct

A
$\frac{{{t_{3/4}}}}{{{t_{1/2}}}} = 3$ [first order reaction]
B
$\frac{{{t_{7/8}}}}{{{t_{1/2}}}} = 3$ [second order reaction]
✓
$\frac{{{t_{7/8}}}}{{{t_{1/2}}}} = \frac{7}{4}$ [zero order reaction]
D
$\frac{{{t_{15/16}}}}{{{t_{1/2}}}} = 15$ [first order reaction]

✓

Answer

Correct option: C.

$\frac{{{t_{7/8}}}}{{{t_{1/2}}}} = \frac{7}{4}$ [zero order reaction]

c
$x = kt$ for zero order $ \Rightarrow \frac{{{t_{7/8}}}}{{{t_{1/2}}}} = \frac{7}{4}$
