    What reaction? Combustion? One of the four acid/base equilibria? Or some fancy organic modification?

    Not that I will be able to answer, but at the moment even someone with PhDenoloftalein degree won't help.

    I should have specified, but the phenolphthalein was mixed with OH-, that still might not be enough information needed.

    I think you need to have 2 of the following to be able to find order of reaction.

    Reaction Rate, Time and Concentration.
