Question

For a particular gaseous reaction a graph was plotted as shown below. It shows that the reaction of A is:

• A. Zero order w.r.t .A
• B. 1st order w.r.t. A
• C. Second order w.r.t. A
• D. a non-integer order w.r.t. A

Answer 1

The correct option is A Zero order w.r.t .A

$\frac{-d\left[A\right]}{dt}=K[A{]}^{\circ }$
$-d\left[A\right]=K\cdot dt$
$\left[A\right]=-Kt+c$
So its zero order reaction
