a)Two reactions have identical values for Ea. Does this ensure that they will have same rate constant if they run at the same tempreture? explain.
b) two simillar reactions have the same rate constant at 25 degress, but at 35 one of the reactios has a higher rate constant than the other. Account for these observations.
