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 $T_1$ is noted. The experiment is again performed using 250 ml of KOH solution and 500 ml of HCl solution and rise in temperature $T_2$ is again noted. Which of the following is correct?

Prashant Kotian · Accepted Answer

Correct answer: D. Exp 1: 1 mole + 1 mole 1 mole water. Total volume = 1000 mL. . Exp 2: 0.5 mole + 1 mole 0.5 mole water (KOH is limiting). Total volume = 750 mL. . Ratio . Thus is 1.5 times larger.
