When adjusted for any changes in ΔH and ΔS with temperature, the standard free energy change ΔG∘T at 500 K is equal to 9.8×104J/mol . Calculate the equilibrium constant at 500 K . Express your answer numerically to three significant figures.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
