The reaction of OH with hydrocarbons initiates the formation of atmospheric aerosols, and is an important elementary step in combustion. The rate constant for the reaction of OH with ethane measured between 822 and 1367K are well fit to an Arrhenius expression with k=(1.11010cm3s1)eT2537K. in contrast, the rate constant for the reaction of OH with ethene is nearly constant with temperature at k=(61012cm3s1). (Enter your answers at least to 3 significant figures.) The probable barrier heights for the ethane reaction is kJmolm1 The probable barrier heights for the ethene reaction is kJmol1 For the OH and ethane reaction, would an OH radical with a speed equal to twice the average speed of OH at 1000K have a chance of having a reactive collision twice the average speed in the Maxwell-Boltzmann distribution for ethane molecules
