Activation energy line on reaction diagram

[BriannaWillingham_1G]

Does the length of the activation energy line on a reaction diagram matter?

[Chem_Mod]

Yes, the longer it is vertically, the higher the activation energy is.

for 4.30 in the 'introduction to organic chemistry'. How do we know that an activation energy of 125KJmol-1 will not occur at room temperature?

[Rachel_Smith_3D]

We know that it won't occur at room temperature because only reactions with an activation energy less than or equal to 80 kJ/mol can occur at room temperature. This is in section 4.3 of the organic textbook.

[Emma Fernandez 1C]

Yes the length of the line on the reaction diagram indicates the amount of activation energy needed for the reaction to occur. This is why when a catalysis is used, the height of the energy line and "hump" decreases, because a catalysis lowers the activation energy in a reaction. Hope this helps!

[Jenifer_Fonseca]

Yes, the line represents the amount of activation energy, this lets us know how fast or slow the chemical reaction is going. For example if we have two different line sizes of activation energy, the longer one would represent that the reaction is happening slowing, now if we compare it to a shorter line we would know that it will happen faster.
