Slowest combustion rate
Webb14 aug. 2024 · Both the forward and reverse reactions for this system consist of a single elementary reaction, so the reaction rates are as follows: forward rate = kf[N 2O 4] and reverse rate = kr[NO 2]2 At equilibrium, the forward rate equals the reverse rate (definition of equilibrium): kf[N 2O 4] = kr[NO 2]2 so kf kr = [NO 2]2 [N 2O 4] Webbmaterial with the slowest combustion rate was wool with 2.39cm2 burned per second, while acetate burned the most quickly, with a combustion rate of 17.52 cm2 burned per …
