rate laws and concentrations :: Chemistry.
A student studied the kinetics of the reaction of sodium hypochlorite and a vegetable dye by the method of pseudo order. He mixed 5 mL of a 0.67 M solution of NaOCl with 15 mL of a vegetable dye, he took a portion of the mixture and absorbance was measured at intervals of 20 ...

Chemistry - Rate Law
The following example is given in my textbook: If a chemical equation is: NO2 (g) + CO (g) -> NO (g) + CO2 (g) The rate law is: Rate = k[NO2]^2 Usually you put in the reactants in their own sets of brackets, so why isn't the reactant CO involved in the rate law? I get it ...

I have these pictures and i have to say which gestalt lawis illustrated, i know some of them are examples of figure/ground which is considered a principle but i dont know if principles are concidered laws(laws which includes similarity, continuity, closure,proximity)
