Answer 1

Answer:

Option B is the correct answer.

Explanation:

=> We know that ,

For. 2A --> product

By Rate law:-

Rate = - ½ {d/dt}[A] = K [A]²

since its of second order

-------------------

Given.

=> Rate constant = K = 9× 10^-5 M L^-1s^-1

=> A = 0.25 M/L

So,

Rate = K [A] ²

= (9×10^-5 )× (0.25)²

= 0.5625 × 10^-5

= 5.6 × 10^-6 M/L s ( answer)
