Question

For an endothermic reaction where ᐃH represents the enthalpy of the reaction in kJ/ mol, the minimum value for the energy of activation will be :

Options

A.less than ᐃH
B.zero
C.more than ᐃH
D.equal to ᐃH

Solution

       
For an endothermic reaction
 Ea = ᐃH + x
x may be taken as energy released in the formation of products from transition state and thus Ea will be always greater than ᐃH in the endothermic reaction it eill be always less than Ea .
