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.

(i) (ii) (iii)

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

• A. 1, 2, 3
• B. 2, 1, ½
• C. 0, 1, 2
• D. 0, 1, ½

Answer 1

Answer: (B)

2, 1, ½

Answer 2

dt is parb parabolic graph of y = x2

So This the graph of second order

y2 = x y = (x) $\frac { 1 } { 2 }$

$\frac{- dc}{dt} = K\lbrack C\rbrack^{\frac{1}{2}}$ So reaction is $\left( \frac{1}{2} \right)$ order.
