In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature. Burn rate is an important parameter especially in the area of propellants because it determines the rate at which exhaust gases are generated from the burni… 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]
