An investigation is carried out in which evidence is collected for the following chemical reaction:?

Question

W+2X + 2Y ---- >> Z
Initial (W) (mol/L) ( 0.10, 0.20,0.10,0.10 )
Initial (X) (mol/L) (0.10, 0.10, 0.20, 0.10 )
Initial (Y) (mol/L) (0.10, 0.10, 0.10 ,0.20)
Rate of Production of (Z) (mol/L.s) ( 12 ,12 ,24 ,48 )

a.) what is the rate law equation for this reaction?
b.) what is the rate-determining step?

Answer 1

Are you in cahoots with the two other questioners or do you have a split personality?

First, you need a model. Try
R(z) = kt, where k = ko * a Xo * b Yo^2
The k model is suggested by the data:
Doubling W did not change k
Doubling X doubled k
Doubling Y quadrupled k
Put in some data:
k = ko ab (0.1)(0.1)^2=12
= ko ab (0.2)(0.1)^2=24
= ko ab (0.1)(0.2)^2 = 48
From this, ab x ko = 12000
