4. At a certain temperature the following data were collected for the reaction

2ICl + H2  I2 + 2HCl.

 
Initial Concentrations (mol L-1)  
  Initial Rate of Formation of
[ICl] [H2] I2 (mol L-1 s-1)
 
0.10 0.10 0.0015
0.20 0.10 0.0030
0.10 0.0500 0.00075
 


Determine the rate law and the rate constant (with correct units) for the reaction.

R = k[ICl]2[H2]2R = k[ICl]2[H2]    R = k[ICl][H2]2R = k[ICl][H2]0R = k[ICl][H2]


What is the value of the rate constant?

-----------------------

The unit of the rate constant is mol L-1 s-1
The unit of the rate constant is s-1    
The unit of the rate constant is M-1s-2
The unit of the rate constant is L mol-1 s-1
The unit of the rate constant is M-2s-1
