If $1.0\,\mathrm{mol}$ of ethanoic acid, $\mathrm{CH_3COOH}$, in aqueous solution undergoes neutralisation with excess aqueous sodium hydroxide, $55\,\mathrm{kJ\,mol^{-1}}$ of energy is given out. Which statement about this reaction is correct?
- AThe reaction is exothermic because only bond breaking takes place.
- BThe reaction is exothermic because only bond forming takes place.
- CThe reaction is exothermic because more energy is given out in breaking bonds than is taken in to form bonds.
- DThe reaction is exothermic because more energy is given out in forming bonds than is taken in to break bonds.
