b(2ab) what will be answer and reason​

Answer 1

Answer:

b(2ab) what will be answer and reason

Step-by-step explanation:

Since (A) is the intermediate reactive species whose concentration is determined from equilibrium step.

Slow step is:

A + B

2

→AB+B (slow)

r = k[A][B

2

]

From equilibrium step

A

⇌A+A(fast)

k

eq

=

[A

]

[A]

2

∴[A]=(k

eq

[A

2

]

1/2

Substitute the value of [A] in equation (i),

r=k.k

eq

1/2

[A

]

1/2

[B

Thus, order of reaction =
