handouts 1-3 bimolecular reactions

Question 1

what is a bimolecular reaction

Answer 1

two molecules involved in the same reaction step

Question 2

differential rate law of bimolecular reaction with 2A = C

Answer 2

vc(t) = -1/2 d[A]/dt = d[C]/dt = k[A]^2

Question 3

solving differential rate law equations of bimolecular molecules 2A

Answer 3

separate variables
with dc/c^2 on one side and -2kdt on the other
solve the integrals

Question 4

what does graph of integrated bimolecular look like 2A

Answer 4

positive slope

Question 5

graph of integrated bimolecular 2A

Answer 5

1/c is y
time is x the slope is 2k
y intercept is c0

Question 6

why not solve differential rate law with separation of variables for [A][B]

Answer 6

c is more than one variable making it horrendously complicated

Question 7

what is a pseudo-first order reaction

Answer 7

when A is in far excess and does not change noticeably so k[A] = keff so treated like first order and find k if we have [A]
