Activation energy `(E_(a))` and rate constants (`k_(1)` and `k_(2)`) of a chemical reaction at two different temperatures (`T_(1)` and `T_(2)`) are related by

Activation energy (E_a) and rate constants (k_1 and k_2) of a chemical reaction at two different temperature (T_1 and T_2) are related by

The rate constants k_(1) and k_(2) of two reactions are in the ratio 2:1 . The corresponding energies of acativation of the two reaction will be related by

A colliison between reactant molecules must occur with a certain minimum energy before it is effective in yielding Product molecules. This minimum energy is called activation energy E_(a) Large the value of activation energy, smaller the value of rate constant k . Larger is the value of activation energy, greater is the effect of temperature rise on rate constant k . E_(f) = Activation energy of forward reaction E_(b) = Activation energy of backward reaction Delta H = E_(f) - E_(b) E_(f) = threshold energy For two reactions, activation energies are E_(a1) and E_(a2) , rate constant are k_(1) and k_(2) at the same temperature. If k_(1) gt k_(2) , then

Two reaction : X rarr Products and Y rarr Products have rate constants k_(1) and k_(2) at temperature T and activation energies E_(1) and E_(2) , respectively. If k_(1) gt k_(2) and E_(1) lt E_(2) (assuming that the Arrhenius factor is same for both the Products), then (I) On increaisng the temperature, increase in k_(2) will be greater than increaisng in k_(1) . (II) On increaisng the temperature, increase in k_(1) will be greater than increase in k_(2) . (III) At higher temperature, k_(1) will be closer to k_(2) . (IV) At lower temperature, k_(1) lt k_(2)

The activation energies of two reactions are E_(1) & E_(2) with E_(1)gtE_(2) . If temperature of reacting system is increased from T_(1) (rate constant are k_(1) and k_(2) ) to T_(2) (rate constant are k_(1)^(1) and k_(2)^(1) ) predict which of the following alternative is incorrect.

Two reactions A rarr products and B rarr products have rate constants k_(a) and k_(b) respectively at temperature T and activation energies are E_(a) and E_(b) respectively. If k_(a) gt k_(b) and E_(a) lt E_(b) and assuming the freuency factor A in both the reactions are same then
