Solution

The correct option is D $m o l l i t r e^{- 1} s e c^{- 1}$
If we observe the decomposition of reactant A with time, we conclude that the decomposition increases linearly with time. Hence, the reaction can be considered to be of zero order and the decomposition at any time $t$ is given by,

$\Rightarrow x = k t$
$k = \frac{x}{t}$

Therefore, unit of $k = m o l s e c^{- 1} l i t r e^{- 1}$
