Answer to Question #156535 in General Chemistry for ash

Question

1. Consider the reaction:

NH4+ (aq) H+ (aq) + NH3 (aq)

Use ΔGf° for NH3 (aq) at 25°C = -26.7 kJ/mol and the appropriate tables to calculate

1. ΔG° at 25°C
2. K at 25°C

Answer 1

• $G=RTlnkd$nkb
• G=8.314 ×298.15 ×-26.7
• G= 66184.47kj/mol
• K at 25= 298.15k
