The correct matching is as follows:
- A. Ethanol has a \( pK \) value of 15.9, so \( A - II \).
- B. Phenol has a \( pK \) value of 10.0, so \( B - I \).
- C. \( m \)-Nitrophenol has a \( pK \) value of 8.3, so \( C - IV \).
- D. \( p \)-Nitrophenol has a \( pK \) value of 7.1, so \( D - III \).
Hence, the correct matching is \( A - II, B - I, C - IV, D - III \).
The Correct Answer is: A-II, B-I, C-IV, D-III
For the thermal decomposition of \( N_2O_5(g) \) at constant volume, the following table can be formed, for the reaction mentioned below: \[ 2 N_2O_5(g) \rightarrow 2 N_2O_4(g) + O_2(g) \] Given: Rate constant for the reaction is \( 4.606 \times 10^{-2} \text{ s}^{-1} \).
Electrolysis of 600 mL aqueous solution of NaCl for 5 min changes the pH of the solution to 12. The current in Amperes used for the given electrolysis is ….. (Nearest integer).
If the system of equations \[ x + 2y - 3z = 2, \quad 2x + \lambda y + 5z = 5, \quad 14x + 3y + \mu z = 33 \] has infinitely many solutions, then \( \lambda + \mu \) is equal to:}
