JEE Mains · Chemistry · STD 11 - 6.2. Equilibrium - II (icon Equilibrium)
Which of the following mixing of 1 M base and 1 M acid leads to the largest increase in temperature?
- A \(30 \mathrm{~mL} \mathrm{CH}_3 \mathrm{COOH}\) and 30 mL NaOH
- B 45 mL \(\mathrm{CH}_3\) COOH and 25 mL NaOH
- C 30 mL HCl and 30 mL NaOH
- D 50 mL HCl and 20 mL NaOH
Answer & Solution
Correct Answer
(C) 30 mL HCl and 30 mL NaOH
Step-by-step Solution
Detailed explanation
The rise in temperature of neutralization reaction will be maximum for maximum number of moles of strong acid and strong base neutralized and lower volume of final solution. (3) \(\mathrm{HCl}+\mathrm{NaOH} \rightarrow \mathrm{NaCl}+\mathrm{H}_2 \mathrm{O}\) mmol \(30 \quad 30\)…
