Solution

The correct option is C $r = - \frac{1}{2} \frac{d [A]}{d t}$
For a General Reaction

$a A \to b B$ , rate is defined as

$r = - \frac{1}{a} \frac{d [A]}{d t}$

Here, $2 A \to 3 C$

So, The Rate 'r' in terms of change of the concentration is given by

$r = - \frac{1}{2} \frac{d [A]}{d t}$
