Question

2. What is the standard free energy change for the following reaction at 25°C? The standard enthalpy change for the reaction is -166.88 kJ.

Answer 1

Answer:

The temperature is 25 deg C or 298 K.

ΔG

o

=−RTlnK=−8.314×298×ln1.3×10

4

=−23469J=−23.4kJ

Hence, the standard free energy change is -23.4 kJ
