Question

The following initial rate data are for the reaction of ICl with hydrogen:

2 ICl + H2I2 + 2 HCl


Experiment [ICl]o, M [H2]o, M Initial Rate, M s-1
1 0.113 3.10×10-2 1.81×10-4
2 0.226 3.10×10-2 3.63×10-4
3 0.113 6.20×10-2 7.25×10-4
4 0.226 6.20×10-2 1.45×10-3




Complete the rate law for this reaction in the box below.
Use the form k[A]m[B]n , where '1' is understood for m or n and concentrations taken to the zero power do not appear. Don't enter 1 for m or n.

Rate =   k_____



From these data, the rate constant is ______M-2s-1.

Expert Solution
Step 1

Given, Chemical Reaction:

2 ICl + H2 ---> I2 + 2 HCl

First, we find the order of Reaction and then the value of rate constant to calculate the rate law expression.
