The gas-phase reaction of NO with F2 to form NOF and F has an activation energy of Ea=6.30kJ/mol and a frequency factor of A= 600108M1s1. The reaction is believed to be bimolecular: What is the rate constant at 569C ? NO(g)+F2(g)NOF(g)+F(g) Express your answer to three significant figures. where NO is a free radical. Free radicals, species with an odd number of unbound electrons, tend to be more reactive. This is one reason by NO reacts so readily with gases such as fluorine or oxygen gas. The activation energy for the reaction NO2(g)+CO(g)NO(g)+CO2(g) is Ea=225kJ/mol and the change in enthalpy for the reaction is H=175kJ/mol What is the activation energy for the reverse reaction? Express your answer with the appropriate units
