Use the following energy profile diagram to answer Questions (a) to (c) below.
(a) From the diagram, determine the value of the; (i) enthalpy of the reaction (ii) activation energy of the reaction.
(b) State whether the profile diagram is for an endothermic reaction or an exothermic reaction.
(c) What name is given to substances which can provide an alternative pathway for the reaction?
(a)(i) Enthalpy = (50 -150) KJ mol\(^{-1}\) = - 100 KJ mol\(^{-1}\)
(ii) Activation energy = (350 - 150) KJ mol\(^{-1}\) = 200KJ
(b) It is for an exothermic reaction
(c) Catalyst or promoters or inhibitors.
