[" An endothermic reaction with high "],[" activation energy for the forward reaction "],[" is given by the diagram: "]

For an endothermic reaction, activation energy for the forward reaction is more/less than activation energy for the backward reaction.

A reaction having equal activation energies for forward and reverse reactions has

For an endothermic reaction, XrarrY . If E_f is activation energy of the forward reaction and E_r that for reverse reaction, which of the following is correct ?
