Given that, for the reaction H+ (aq) + OH- (aq) H2 O (I), energy released is 57.1 kJ. Three reactions are given as follows
(1) 0.25 mole of HCI in solution is neutralized by 0.25 mole of NaOH; heat released is Δdiv.
(2) 0.5 mole of HNO3 in solution is mixed with 0.2 mole of KOH solution; heat released is ΔH2.
(3) 200 cm3 of 0.2 M HCI solution is mixed with 300 cm3 of 0.1 M NaOH solution heat released is ΔH3.
The correct order for the numerical value of Δdiv, ΔH2, ΔH3 would be?
