Consider an eendothermic reaction XrarrY with the activation energies E_(b) and E_(f) for the backward and forward reaction, respectively. In general

When the activation energies of the forward and backward reactions are equal, then :

For the reaction, for which the activation energies for forward and backward reactions are same, then:

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 In a hypothetical reaction A rarr B , the activation energies for the forward and backward reactions are 15 and 9 kJ mol^(-1) , respectively. The potential energy of A is 10 kJ mol^(-1) . Which of the following is wrong?
