Vedclass · Answer

(B) The enthalpy of neutralization for $1 \ g$ equivalent of a strong acid with a strong base is constant at $13.7 \ kcal$. Since the volumes and molarities are equal,let the volume be $V \ L$ and molarity be $M \ M$. For $HCl$,the number of equivalents is $M 	imes V 	imes 1 = MV$. For $H_2SO_4$,the number of equivalents is $M 	imes V 	imes 2 = 2MV$. Since $H_2SO_4$ provides twice the number of equivalents of $H^+$ ions compared to $HCl$,the heat liberated by $H_2SO_4$ $(y)$ will be twice the heat liberated by $HCl$ $(x)$. Therefore,$y = 2x$ or $x = \frac{y}{2}$.

Equal volumes of molar hydrochloric acid and sulphuric acid are neutralized by dilute $NaOH$ solution and $x \ kcal$ and $y \ kcal$ of heat are liberated respectively. Which of the following is true?
