Work all the parts to get the most points. 1 pt An energy versus reaction progress diagram is shown below. Select the activation energy and enthalpy change which could be represented by the diagram. 1 pt s 200 100 Products Reactants Reaction progress (Select all that apply.) HP = 90 k/ mol-1. Ea = 250 kJ mol-1 HP = 90 kJ mol-1 ; Ea = 160 kJ mol-1 OHP-250 kJ mol-1 ; Ea-90k/mori Submit Submit Answer Try Another Version 5 item attempts remaining Email nstructor Save and Exit nent

Explanation / Answer

delta H = energy of product - energy of reactant
= 100 KJ/mol - 10 KJ/mol
= 90 KJ/mol

Ea = energy of activated complex - energy of reactant
= 260 KJ/mol - 10 KJ/mol
= 250 KJ/mol
