Question

ReactionA+B→kC+DA+B→kC+Dfollows the rate lawr=k[A]1/2[B]1/2r=k[A]1/2[B]1/2 where k is given. Starting with 1M ofA and B each, what is the time taken for concentration ofA Ato become 0.1M?

Answer 1

To find the time taken for the concentration of A to become 0.1M in the given reaction, we can use the integrated rate law for a second-order reaction.

Step-by-step explanation:

The given reaction follows the rate law r=k[A]1/2[B]1/2. Starting with 1M of A and B each, we want to find the time taken for the concentration of A to become 0.1M.

To solve this problem, we can use the integrated rate law for a second-order reaction:
[A] = [A]0 - kt

Substituting the given values, we have:
0.1M = 1M - k * t

Simplifying the equation and solving for t, we get:
t = (1M - 0.1M) / k

To find the time taken for the concentration of A to become 0.1M in the given reaction, we can use the integrated rate law for a second-order reaction.
