MEASURING RATE OF REACTION BY A CONTINUOUS METHOD BETWEEN HCL AND MAGNESIUM
this is required A level practical

there is a question about it and i am confused on it
in question, he says that
one problem with this practical is that it is exothermic reaction .and asked how might this affect your final result and how could modify your experiment to reduce this problem

use some insulation to minimise heat loss

effect on the result is that we get the less accurate value of the rate of reaction than actually, it is

i think

You a confusing enthalpy change calorimetry with rates determination.

The practical you described looks like it is to try to find the effect of changing conc of an acid on rate of reaction with Mg.

Will it be a fair test if T also changes?

Can you explain to me please?

What are the four main factors that affect the rate of reaction between an acid and a metal?
So if you are loosing the heat from the reaction then the rate od reaction will decrease
