In a study conducted at the same temperature, the following data for reaction producing nitrosyl bromide were collected.

Part C

What is the rate of the reaction when the initial concentration of NO is 0.400 M and that of Br2 is 0.235 M ?

Solution

from the given data rate law as foloows

rate = K [NO]²[Br2]

K = rate / [NO]² [Br2]

K = 48 / [0.150]² [0.240]

K = 48 / 0.0054

K = 8.89 x 10³ M^-2 s^-1

now [NO] = 0.400 M

[Br2] = 0.235 M

rate = 8.89 x 10³ [0.400]² [0.235]

rate = 3.34 x 10² M/s
