Question

Select the rate law that corresponds to the data shown for the following reaction. A+B Products Experiment [A] (mol dm3) 0.01

Answer 1

Answer #1

see experiment 1 and 3:

[A] doubles

[B] is constant

rate is constant

so, order of A is 0

see experiment 1 and 4:

[A] is constant

[B] doubles

rate becomes 8 times

so, order of B is 3

overall order = 0 + 3 = 3

Rate law is:

rate = k*[B]^3

Answer: option 1

Answer 2
