Homework Statement
Consider the following reaction at 282 K.
2 A + 2 B → C + D
where rate = rate=k[A]2. An experiment was performed for a certain number of seconds where [A]0 = 0.000303 M and 0 = 1.63 M. A plot of ln[A] vs time had a slope of -7.27. What will the rate of this reaction be when [A] = = 0.503 M?
Rate (M/s)=
The correct answer is 0.348 M/s.
Homework Equations
I'm not sure where to start here, but I tried using these equations, because I was given the slope, and the slope for ln[A] vs time is given in a first order reaction:
ln[A]t = -kt + ln[A]o
Rate = k[A]
k = -slope
The Attempt at a Solution
Basically I just tried plugging into k = 7.27 into rate=k[A]2 were [A] and are both 0.503 M.
Thank you for the help!
