activation energy is "treshold energy - ground state energy"

OR

"threshold energy-intial potential energy"

OR

"thresold energy -initial kinetic energy"

i want to know which one the above are true

and if 2nd and 3rd are true then what do they mean by"initial kinetic energy and intial potential energy"

do initial kinetis energy and initial potential energy are calculated at S.T.P. OR N.T.P?

PLEASE GIVE ME CLARITYIN THIS TOPIC ,.

OUR TEACHERS ARE UNABLE TO UNDERSTAND ALL THESE DOUBTS AS WELL AS THEY ARE UNABLE TO CLEAR THSE DOUBTS

THANKS A LOT FOR THE IITIAN WHO GIVES A CLARITY FOR ME ABOUT THIS QUESTION

dear nikhil,

All matter is made up of molecules. Many molecules can peacefully co-exist almost indefinitely. Some molecules, however, cause some kind of reaction when they come into contact with certain molecules. For this reaction to occur, the molecules must be brought extremely close together and in a particular orientation. Activation energy is also involved in many reactions, because typically, reactions also involve the breaking of pre-existing bonds.

BEST OF LUCK..!!!!
