Question

A general reaction written as 1A + 2B --> C + 2D is studied and yields the following data:
Expt (A). (B) initial (C)/t
1. 0.150. 0.150. 8.00 x10^-3
2. 0.150. 0.300. 1.60 x10^-2
3. 0.300. 0.150. 8.00 x10^-3


What is the order of the reaction with respect to B?
What is the order of the reaction with respect to A?
Determine the initial rate of B consumption (delta(B)/delta t) for the first trial?

Answer 1

rate exp 2 = k1*(A)^x(B)^y
--------------------------
rate exp 1 = k1*(A)^x(B)^y

Now plug in values for exp 1 and exp 2. That will give you
1.60E-2 = k1*(0.300)^x*(0.0.150)^y
--------=-------------------------8.00E-3 = k1*(0.15o)^x(0.150)^y

k1 cancels.
0.150)^y cancels and you are left
2 = (0.300)^x/(0.150)^y and becomes
2 = 2^x so x must be 1 and that's the order of B.
Can you handle the rest of it. This is how you do it.
