Question

For a reaction glutamate + NH3 → glutamine + H2O that occurred at 20⁰C, calculate the Gibbs free energy change of the reaction. Given the change in enthalpy of 3103 cal and change of entropy of 3.4 cal/K

Answer 1

$\Delta G= \Delta H - T\Delta S$

$T= 20°C=293K$

$\Delta H=3103cal$

$\Delta S=3.4cal/K$

$\Delta G=3103-293×3.4= 2106.8cal$
