Question

The enthalpy of neutralization is about 57.3 kJ for the pair

• A. $\Delta G = 0,\Delta E = 0$ and $\Delta G = - ve,\Delta E = 0$
• B. $\Delta G = + ve,\Delta E = + ve$ and $\Delta G = - ve,\Delta E = + ve$
• C. $\Delta H = 31400ca;$ and $\Delta S = 32calK^{- 1}mol^{- 1}$
• D. $1000^{o}C$ and $\Delta H$

Answer 1

Answer: (C)

$\Delta H = 31400ca;$ and $\Delta S = 32calK^{- 1}mol^{- 1}$

Answer 2

Heat of neutralisation between strong acid and a strong base is about $\Delta S = 32calK^{- 1}mol^{- 1}$
