The notion of long chain hydrocarbons surviving cooking for millions of years is absurd regardless of pressure. There is no reversible chemistry involved where chain breaking is in equilibrium with chain re-forming. There is enough thermal energy available to break the chains into smaller and smaller units. These smaller pieces do not re-assemble since there is a high Gibbs free energy barrier. Pressure does not stop this process since pressure is not chemistry and just keeps the stew in the pot.
The reason we can burn these long chain hydrocarbons is because their chains can be broken relatively easy and there is a net energy release in the process. Of course without an oxidant there is a Gibbs free energy barrier but it is not high. If it was high, then the exothermic oxygen combustion chemistry would not apply.
By Bojan Pancevski and Jenny Strasburg BERLIN Germany, France and Italy joined a group of smaller European countries that have temporarily stopped administering Covid-19 vaccines made by AstraZeneca PLC, saying the move was precautionary amid a small number of cases of blood clotting reported on the continent. Denmark last week said it had paused AstraZeneca shots for two weeks following reports of blood clotting, and several other European countries quickly followed suit, saying they were doing so out of an abundance of caution. Norway, Ireland and the Netherlands are among countries that have paused vaccinating with AstraZeneca s shot. Health regulators in the U.K. and Europe, along with AstraZeneca and its vaccine development partners at the University of Oxford, say there is no known connection between severe clotting and the shot. AstraZeneca has said the number of cases of blood clotting among the roughly 17 million people in the European Union and U.K. w
