Q3 Single Correct Medium
Mayuri was performing thermometric titration and she took $100\ ml$ of $1\ m$ sulphuric acid and started adding $1M$ calcium hydroxide and she plotted a graph of temperature vs volume of the titrant added. In that experiment she found that temperature was initially increasing and then it started decreasing. The maximum of the graph is obtained at $100\ ml$. Calcium hydroxide. What will be the enthalpy change of this reaction. [Given $\triangle H = -13.7\ kcal$ for equivalent].
• A. $-13.7\ kcal$
• B. $-27.4\ kcal$
• C. $-1.37\ kcal$
• D. $-2.74\ kcal$
