Question

Type 1	Type 2
I. $S{O}_{2}C{l}_2\to S{O}_2+C{l}_2$	a. pseudo unimolecular reaction
II. $2N{O}_2\to 2N_2+O_2$	b. first order reaction
III. $2NO+O_2\to 2N{O}_2$	c. second order reaction
IV. $C{H}_{3}COO{C}_2{H}_5+H_{2}O+H^{+}\to C{H}_{3}COOH+C_2{H}_{5}OH$	d. third order reaction

The correct matching is :

• A. I - a, II - b, III - c, IV - d
• B. I - b, II - a, III - d, IV - c
• C. I - d, II - c, III - b, IV - a
• D. I - b, II - c, III - d, IV - a

Answer 1

Answer: (D)

I - b, II - c, III - d, IV - a

$rate=k\left[S{O}_{2}C{l}_2\right]$

$rate=k[N{O}_2{]}^2$

$rate=k\left[NO{]}^2\right[O_2]$

$rate=k\left[C{H}_{3}COO{C}_2{H}_5\right]$$\left[H_{2}O\right]=k^{\prime }\left[C{H}_{3}COO{C}_2{H}_5\right]$

So,

$I\to b$
$II\to c$
$III\to d$
$IV\to a$
