Vedclass · Answer

(D) The rise in temperature of the solution during neutralization is directly proportional to the enthalpy of neutralization. For strong acid and strong base,the enthalpy of neutralization is $-57.1 \ kJ \ mol^{-1}$. For weak acids,some energy is consumed in the dissociation of the weak acid,resulting in a lower enthalpy of neutralization compared to strong acids. However,the question asks for the maximum rise in temperature. Among the given options,$HNO_3$ is a strong acid,while $HCN$,$CH_3COOH$,and $H_2S$ are weak acids. Since the enthalpy of neutralization for a strong acid $(HNO_3)$ is the highest,it will release the maximum amount of heat,leading to the maximum rise in temperature.

When one equivalent of an acid is mixed with an excess of a strong base,which of the following acids will show the maximum rise in the temperature of the solution?
