A catalyst decreases the activation energy of a particular exothermic reaction by 56 kJ/mol, to 35 kJ/mol. Assuming that the mec
hanism has only one step, and that the products are 78 kJ lower in energy than the reactants, sketch approximate energy-level diagrams for the catalyzed and uncatalyzed reactions. What is the activation energy for the uncatalyzed reverse reaction
Tick Volume Definition Tick volume is measuring every trade whether up or down and the volume that accompanies those trades for a given time period. If you are a day trader or a short term swing trader, tick volume analysis will assist you in sizing up the market on an intraday basis.
