For the given set of statements it should be identified that whether they are true or false to the given respective given chemical reaction and the false the statements are should be explained. Concept introduction: Hydrogenation: The addition of hydrogen to unsaturated compounds to convert into saturated compounds in the presence of catalyst. Catalyst: The catalyst is a chemical substance that increases the rate of the reaction without participating in the reaction by reducing the activation energy of the reaction. Collision theory: The rate for the reaction is predicted by using collisions theory. In order to form bond the atoms present in the reactants should collide each other for the bond formation.
