Activation energy line on reaction diagram

Postby BriannaWillingham_1G » Thu Mar 03, 2016 5:17 am

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

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?

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.
