The equilibrium constant for the following reaction Ag+(aq) + 2NH3(aq) Ag(NH3)2+(aq) is K = 1.7 × 107 at 25°C. What is ΔG° at this temperature? Question 10 options: a) –1.5 kJ b) –23 kJ c) –41 kJ d) –3.5 kJ e) –18 kJ
Homework Answers
given
K = 1.7 × 107
T= 25 C = 298 K
gas constant R = 8.314 J mol-1 K-1
then equation to connect deltaG0 anfs equilibrium constant
is
delta G0 = -RT ln K
= -8.314 J mol-1 K-1 *298 K ln1.7 × 107
=- 41248 J = -41 KJ
Answer
c) –41 kJ
