Question

In three different reactions, involving a single reactant in each case, a plot of rate of the reaction on the $y$-axis, versus concentration of the reactant on the $x$-axis, yields three different curves shown below.

What are the possible orders of the reactions (i), (ii), (iii).

• A. 1,2,3
• B. 2,1,1 / 2
• C. 0,1,2
• D. 0,1,1 / 2

Answer 1

Answer: (B)

$dt$ is parb parabolic graph of $y=x^2$

So This the graph of second order
$y^2=xy=(x)\frac{1}{2}$
$\frac{-dc}{dt}=K[C{]}^{\frac{1}{2}}$
So reaction is $\left(\frac{1}{2}\right)$ order.
