$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

Will there be a difference in my answer if I calculate Gibbs free energy using the formula for products minus reactants or if I use the formula including enthalpy?

There might be differences but it shouldn't be drastically different. These differences could arise from the delta G changing for products and reactants based on the environment, or because the delta H might be slightly off because its being used for a wide variety of temps
