So I was fiddling with making a new reaction using hydrogen peroxide and I stumbled across that the activation energy in game of hydrogen peroxide was the same as the enthalpy of the reaction (disregarding the sign of course) at 196 kj/mol.
This didn't seem right so after a bit of searching I found this link: chemed.chem.purdue.edu/demos/demosheets/19.6.html it indicates that the value should be more in line with 75 kj/mol without a catalyst or 49 kj/mol with a platinum catalyst (which would be likely in an engine but could be reserved for bipropellant mixtures to avoid tanks being a bit too explosive).
I've tried to find more sources on the data but come up empty handed, however it's very unlikely that the enthalpy of the reaction would be the same as the activation energy as it would make a chain reaction in this basically unsustainable, which many accidents have prooven that it isn't.
