It is a Zero Order Reactionk-A0-x2212-A-t2-xD7-10-x2212-2-A0-x2212-0-5-25-A0-1-xA0-MHence- the correct option is D

K for a zero order reaction is $2 \times 10^{- 2} L^{- 1} {S e c}^{- 1}$ . If the concentration of the reactant after 25 sec is 0.5 M, the initial concentration must have been.
0.5 M
1.25 M
1.0 M
12.5 M

It is a Zero Order Reaction

$k = \frac{[A_{0}] - [A]}{t}$

$2 \times 10^{- 2} = \frac{[A_{0}] - [0.5]}{25}$

$[A_{0}] = 1 M$

Hence, the correct option is $D$
