For a reaction: aA + bB --> cC + dD How do i find the parts stated below in the details of this question?
aA + bB --> cC + dD
then it is found that the Rate a [C]m[D]n
Rate = k [C]m[D]n
a.What is the order of the reaction w.r.t. reactant C?
b.What is the order of the raction w.r.t. reactant D?
c.What is the overall order of the reaction?
d.What is âkâ?
Answer:
a. (m) is the order of the reaction, the order is what the conc. of the reactant is powered to, so it is written [C]^m not [C]m , it is not multiplied, it is given to be a power of [C].
b. (n)
c. it is m+n , in other words, it is the sum of all individual orders of reactions.
d. "k" is the reaction constant, it only changes its value for this reaction when temprature changes.
I think for the above reaction according to law of mass action---
reaction rate = k[A]^a [B]^b
(check ur question)
But anyways ur answer will be--
order of reaction w.r.t C = c
order w.r.t D = d
over all order = c+ d
Here 'k' is a constant and is called Reate constant or specific reaction rate or velocity constant
