Question
A solution of 500 ml of 2 M-KOH is added to 500 ml of 2 M-HCl and the mixture is well shaken. The rise in temperature T1 is noted. The experiment is again performed using 250 ml of KOH solution and 500 ml of HCl solution and rise in temperature T2 is again noted. Which of the following is correct?
Options
A.T1 = T2
B.T1 is 2 times as larger as T2.
C.T2 is twice larger as T1.
D.T1 is 1.5 times as larger as T2.
Solution
$q = (1000 \times d) \times s \times T_{1}$
$\therefore\frac{q}{2} = (1000 \times d) \times s \times T_{2}$ (KOH is limiting reagent)
$\therefore T_{1} = 1.5\ T_{2}$
