D. It is the ratio or reactants to products.
Homework Answers
Ans 1
The given rate
![Product Formation Rate = k[A]*[B]”[C]”](http://img.homeworklib.com/questions/daaca150-5c0e-11eb-9df2-17c4c10dd87f.png?x-oss-process=image/resize,w_560)
x = 2
y = 1
z = 0
Overall reaction order = x + y + z
= 2 + 1 + 0
= 3
Option D is the correct answer
Ans 2
A, B and C all are reactants
Its a third order reaction, it's units L2 mol-2 s-1
k represents the rate constant of the reaction and depends on the temperature.
Option C is the correct answer
