    Hi I've been doing an Iodine clock reaction using catalysts and ranging the temperature to find the rate constant and activation enthalpy.

    The results show that Fe 3+ has a considerably higher Ea than Fe2+, why is this?

    Cheers in advance,

    Fe3+ is more reactive than Fe2+ because it has one less electron in the valence shell

    If iron(III) has a higher activation energy than iron(II) to reaction then it is LESS reactive ...
