Question: (a) Two reactions have identical values for Ea. Does this ensure that they will have the same rate constant if run at the same temperature?

(a) Two reactions have identical values for Ea. Does this ensure that they will have the same rate constant if run at the same temperature? Explain.
(b) Two similar reactions have the same rate constant at 25 oC, but at 35 oC one of the reactions has a larger rate constant than the other. Account for these observations?
