Question

The reaction below was investigated and the data in the table collected.

a) What is the order with respect to each reactant and the overall order of the

reaction? Order with respect to A: Order with respect to B: Overall reaction order:

b) Write the rate law for the reaction

c) From the data, determine the value of the rate constant. Make sure that you specify the units of the rate constant.

d) If the rate of disappearance of B is equal to 0.25 M/sec, what is the rate of appearance of C?

PLease show your work. This is from my review for an exam. Thank you.

The reaction below was investigated and the data in the table collected.

a) exp 2/ exp1 ( 0.24/0.12)^b = 0.04/0.01 = 4 ,

b =2 , hence order with respect to B = 2

exp 3/exp2 = ( 0.45/0.15)^a = 1.08/0.04 = 27

a = 3 = order with respect to A ,

overall order = 2+3 = 5

b) rate law is rate = k[A]^3[B]^2

c) by exp1 0.01 = k(0.15)^3(0.12)^2 , k = 205.76 M-4 s-1

d) -dB/dt = 0.25

but (-1/2) dB/dt = (1/3 )dC/dt

dC/dt = 3 /2( -dB/dt )= (3/2)(0.25) = 0.375 M/sec
