1. ln【A】= -3.344 【A】=?
2. A certain reaction has an activation energy of 54.0 KJ/mole. As the temperature is increased from22℃ to a higher temperature, the constant increases by a factor of 7.00. Calculate the higher temperature.
3. Ea for the uncatalyzed reaction O3(g)+O(g)迳2O2
Is 14.0 KJ.Ea for the same reaction when catalyzed is 11.9kJ. what is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction at 25℃? Assume that the frequency factor A is the same for each reaction.
