The reaction 2A -> B is first order in A with a rate constant of 8.42 x 10-2 s-1 at 800oC. How long it will take for A to decrease from 5.00 M to 0.153 M?

41.4 s

Explanation:

Given data

Let's consider the following reaction of first order with respect to A.

2 A ⇒ B

We can find the time that it will take for A to decrease from 5.00 M to 0.153 M using the following expression.
