To find the order with respect to a reagent, compare experiments where only that reagent's concentration changes.
They have identical chemical properties because they have the same electronic configuration. : chemsheets 1232 answers
Always remember that the bromine water test distinguishes between alkanes (no color change) and alkenes (decolorizes). To find the order with respect to a
