Description

Show an energy diagram with values. Reactants at 100 kJ, Transition state at 250 kJ, Products at 50 kJ. Q1: 'ΔH = products - reactants = 50 - 100 = ___ kJ' (-50). Q2: 'This reaction is ___ (exo/endothermic)' (exothermic). Q3: 'Ea (forward) = transition state - reactants = 250 - 100 = ___ kJ' (150).
