Answer:
Kindly find the attached image.
Explanation:
Activation energy: is the difference in potential energy between the activated complex and reactants.
Enthalpy of reaction: is the difference in potential energy between the products and reactants.
Answer:
"Electronegativity" decrease moving from the bottom of Group 3 to the top of Group 3
Explanation:
Electronegativity of an element tell us about the ability of an atom to attract the electrons towards the atom. It depends upon the atomic number and also the distance between the valence electrons that is present in the charged nucleus. The electronegativity will increase from left to right while moving in the periodic table. Electronegativity decreases from bottom to top. To measure the electronegativity pauling scale is used.
