Question

In effect of concentration on rate,why is it important to

havethe same potassiumin four reaction mixtures?

Answer 1

Step-by-step explanation:

If we change the concentration of Potassium since we take KI solution, concentration of I- changes, then the rate changes accordingly

Rate = k[H2O2 ]^a[I-]^b [H+]^c

The concentrations of I- and H+ are held constant in the procedure

thus to study the rate of the reaction, concentration of KI solution has to be constant only the peroxide solution varies.
