When I ad 50%NaClO3 sol with a reductor like CH3OH and a drop of Co II sol oxidation occure ( production of CO2 gas) but no heat or other form of
energy seem to be maked, normaly when an oxidizer and a reductor react together they make heat or ligth.... Where the energy goes?
Thanks!!!

May be the heat is removed by the CO2 which escapes the solution?

There is some thermal energy released, only you are unable to measure it. Might be because your methods are not suitable.
Thermodynamic system can relieve itself in many ways. Expelled carbon dioxide is a great way of doing it. Our bodies expell, among other matter in a
high state of disorder, carbon dioxide. That keeps them in a relatively highly ordered state compared to the environment. That mechanism is powered by
ingestion of energy rich matter which reacts in our cells.
Try to do it on a larger scale and use a digital thermometer. You should read out a change in temperature.
And try to measure the volume of the gas.

Yeah, same reason HCl and baking soda react vigorously, yet the reaction actually chills the solution. You're creating a state change.

I repeat the process but this time I ad much lower amont of catalist and I see on my termometer a temperature diference. Thank you all ,I will make
update and picture.
