A chemistry student needs to determine the new equilibrium concentration of a complex ion, if the temperature is increased by 10°C from the initial temperature of 25°C, and the equilibrium constant for the reaction is 0.056. The initial concentration of the reactants are: [Fe3+] = 0.025 M, [SCN-] = 0.015 M, and [FeSCN2+] = 0.007 M.
