At a certain temperature the following data were collected for the reaction 2ICI + H2 + 12 + 2HCI. Initial Concentrations (mol L-2) Initial Rate of Formation of 12 (mol L ) (ICI) [H21 0.10 0.20 0.10 0.10 0.10 0.0500 0.0015 0.0030 0.00075 Determine the rate law and the rate constant (with correct units) for the reaction. O R = K[ICI]2[H21 R = K[IC][H21 O R = K[ICI][H21 OR = K[IC] [H212 O R = K[IC][H212 What is the value of the rate constant? The unit of the rate constant iss! The unit of the rate constant is L mol-1 s-1 The unit of the rate constant is mol L-15-1 The unit of the rate constant is M-15-2 The unit of the rate constant is M-25-1
