Hydrogen-induced methane lifetime response
= Hydrogen-induced methane lifetime response
In a fixed-production <hydroxyl radical> box, adding hydrogen by $\Delta[\mathrm H_2]$ changes $K$ to $K+k_{\mathrm H_2+OH}\Delta[\mathrm H_2]$. <Methane> lifetime scales as $K/P$ when its <hydroxyl radical> reaction coefficient is held fixed. The pre-existing hydrogen contribution is already in $K$ and must not be counted again.
