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 the following reaction at a particular temperature, according to the equations
`2N_(2)O_(5) rarr 4NO_(2)+O_(2)`
`2NO_(2) + (1)/(2)O_(2) rarr N_(2)O_(5)`
The activation energies are `E_(1)` and `E_(2)`, respectively. Then

A

`E_(1)gtE_(2)`

B

`E_(1)ltE_(2)`

C

`E_(1)=2E_(2)`

D

`sqrt(E_(1)E_(2)^(2))=1`
