Comparison of the net reaction rate in hydrogen containing carriers with nitrogen or argon shows that the main decomposition pathway (reaction 21, Table ) is suppressed in hydrogen. The large amount of available hydrogen will result in reaction 21 to have a high reverse rate, causing its equilibrium to be shifted towards ammonia, and thereby limiting the decomposition rate. As more hydrogen is decomposed into radicals, reaction 21 will start to dominate and be the main decomposition pathway, with reaction 22 being the second most important, similar to in argon or nitrogen carriers.
