## Homework Statement

2A + 2B -> C +D

where rate = k [A]

**^2**

[A]_0 = .000443 M

[A]_0 = .000443 M

**_0 = 1.69 M**

A plot of ln [A] vs time has a slope of -9.87. What will the rate of this reaction be when [A]=A plot of ln [A] vs time has a slope of -9.87. What will the rate of this reaction be when [A]=

**=1.412 M?**

From given information, this is pseudo-first order. So slope=-k so k = 9.87 but this is pseudo-order so k'= 9.87

rate= k' [A]

k' = k## Homework Equations

## The Attempt at a Solution

From given information, this is pseudo-first order. So slope=-k so k = 9.87 but this is pseudo-order so k'= 9.87

rate= k' [A]

k' = k

**^2 --> k = k' /****^2 and I plug in the values for k' and****= 1.412 and I get the wrong answer. The answer should be 9.73 M/s**
