The activation energy for the isomerization reaction of CH 3N C: CH 3 NC ⇀ CH 3C N is 161 kJ/mol, and the reaction rate constant at 600 K is 0.41 s- 1 . Calculate the Arrhenius factor A for this reaction. Calculate the rate constant for this reaction at 1000 K and assume that the activation energy and A do not change with temperature.
A certain reaction has an energy change of AE = +29 kJ and an activation energy of B = 56 kJ. What is the activation energy of the reverse reaction?
INFORMATION reaction must also be perimental mea data are plotted in the sult means that the rate Because a reaction is faster at higher temperatures, the rate constant for the reaction m larger. The activation energy of a reaction can therefore be determined from experime surements of the rate constant at several temperatures. When the collected data are ple form In(k) vs T. as shown in Figure 2. a straight line is produced. This result means constant varies exponentially with...
