However, from the steps i introduced, i realise that the
overall conductivity = drop in conductivity of NaOH + increase in Conductivity of CH3C00Na,

Hence, the difference of overall conductivity consist part of " some" conductivity of CH3COONa, hence, is it still possible to use it?

Yes, it is covered by the ax + b(0.01-x) - ax is the CH3C00Na increase, b(0.01-x) is the NaOH drop.

Note that what is really happening is that OH- is replaced by CH3COO-, as Na+ concentration doesn't change.

Hi i am doing the same experiment as well.
But I can't figure out how am I going to obtain the rate law through the method of excess as i do not have the concentration of ethyl acetate, i would be unable to use the integral method to find the order of reaction with respect to ethyl acetate. And i can't figure out how to find K as well if i use the method of excess as K in the method of excess is different from the K in the rate law.
