The minimum amount of energy required for the reacting molecules to undergo reaction is called :
threshold energy.
Increase in the concentration of the reactants leads to the change in
Collision frequency
Energy of activation of an exothermic reaction is
Positive Activation energy is always Positive
The chemical reactions in which reactants require high amount of activation energy are generally ................
Slow
The rate of reaction increases with increase of temperature because ...
an increase in the number of activated molecules.
The activation energy of reaction is equal to
Threshold Energy – Energy of the reactants
Collision theory is most satisfactory for __________ reaction.
Bimolecular
If $E_f$ and $E_r$ are the activation energies of the forward and reverse reactions and the reaction is known to be exothermic then
$ E_f \lt E_r $
