Problem
The table below lists the molar enthalpy change (ΔH) for four chemical reactions measured at constant pressure.
Reaction ΔH (kJ mol−1)
A −45
B +35
C −110
D +12
Assuming one mole of reactant undergoes the reaction in each case, which reaction is most likely to raise the temperature of the surrounding water by the greatest amount?
(a) A
(b) C
(c) D
(d) B
