For exothermic reversible reaction activation of forward direction depends upon ETEA2019

According to collision theory of a bimolecular chemical reactions in gas phase, minimum amount of energy required for an effective collision is known as MDCAT2011 

If the energy of activation of a chemical reaction is very low, the rate of that chemical reaction is observed to be very high because MDCAT2019

If energy of activated complex is close to energy of reactants, it mean that the reaction is NUMS2019

A reaction having equal activation energies for forward and reverse
reaction has [MP PMT 2002]

An endothermic reaction A → B has an activation energy 15kcal /mole and energy of reaction 5 kcal /mole
.The activation energy of the reaction B → A is [Pb. CET 1985] 

The minimum energy a molecule should possess in order to enter into a fruitful collision is known as
