In an endo-ergic reaction the binding energies of reactants and products are `E_(1), E_(2)` respectively

In an exo-ergic reaction the binding energies of reactants and products are E_(1), E_(2) respectively then

A reaction is separately carried out in absence and presnce of a catalyst . If the activation energies in presnce and absence of catalyst are E_(a) and E'_(a) respectively and the reaction-enthalpies are DeltaH' respectively , then-

The binding energies of the atom of elements P and Q are E_(P) and E_(Q) respectively. There atoms of element Q fuse on atom of element P . The correct relation between E_(P), E_(Q) and e will be

The energy required to form the intermediate, called activated complex (C ) is known as activation energy (E_(a)) . The diagram is obtained by plotting potential energy vs. reaction coordinate. Reaction coordinate represents the profile of energy change when reactants change into products. Some energy is released when the complex decomposes to form products. So, the heat of the reaction depends upon the nature of reactants and products. If a reaction A+Brarr C , is exothermic to the extent of 30 kJ mol^(-1) and the forward reaction has an activation energy of 249 kJ mol^(-1) , the activation energy for reverse reaction in kJ mol^(-1) is:

If m_(1) and m_(2) are masses of two reactants in any reaction, having their gram equivalent masses E_(1) and E_(2) respectively, which of the following equatios represents the law of equivence correctly?
