    Activation energy for a chemical reaction

    hi, could some one please verify what i have done here or tell me where i went wrong. suppose the activation energy for a chemical reaction is E*, i have to work out how the rate of the forward reaction depends on temperature T and concentration. (note: i am given the Boltzmann distribution...

    How do enzymes lower the free energy of activation?

    Hey guys; I've a question. How do enzymes lower the free energy of activation? My thinking is that the enzyme binds, and when it binds it alters the shape of whatever it binds to, and the altered shape is energetically favored to the unaltered shape for the reaction. This is purely...

    Calculating Activation Energy for X+Y -> XY Reaction

    is there a way to tell the activation energy for a reaction mathmatically just based on what the reaction is, or what it contains? or do you just have to know what it is, based on looking off a table or some other way of finding that data. lets say I have a hypothetical reaction: X + Y -> XY...
