For an elementary reaction, 2A + B C + D the molecularity is - Vidyadip

MCQ

For an elementary reaction, $2A + B \to C + D$ the molecularity is

A
$0$
B
$1$
C
$2$
✓
$3$

✓

Answer

Correct option: D.

$3$

d
(d) $2A + B \to C + B$

Rate $= k{[A]^2}{[B]^1}$

$\therefore $ O.R. $= 2 + 1 = 3$ and molecularity is $3[2A + B]$.
