4. The activation energy, E., for a reaction A B, was found to be 35.6 kJ/mol. If the rate constant at 25 C is 3.6 x 10^s!, what is the rate constant at 300 C? V 5. The linear plot" of data for a reaction with only one reactant is shown below for two different experiments. a) What must the order of this reaction be (assuming only zero, Ist, or 2nd order)? b) What TWO variables changed between Experiments 1 & 2? t(sec) 6. The following figure shows Arrhenius plots for four different reactions. a) Which reaction has the smallest frequency factor? b yu b) Which reaction has the largest activation energy? d VT
