For the reaction C H 3 C O O H ( l ) + C 2 H 5 ( l ) ⇌ C H 3 C O O C 2 H 5 ( l ) + H 2 O ( l ) the value of equilibrium constant (K) is 4 at 298 K. The standard free energy change ( Δ G ° ) is equal to
Options
- A3.473   kJ   mol − 1
- B− 34730   kJ   mol − 1
- C34730   kJ   mol − 1
- D− 3.473   kJ   mol − 1
Correct answer
D. − 3.473   kJ   mol − 1
Step-by-step solution
ΔG o = − 2 .303 RT log K = − 2.303 × 8.314 × 298 log 4 = − 3473 J mol − 1 = − 3.473 kJ mol − 1
