A chemistry student needs to determine the effect of increasing the temperature on the equilibrium constant of the formation of a complex ion. Given the equation: Fe3+ + 4OH- ↔ Fe(OH)4- Kc = 2.1 x 10^-18 If the initial concentration of Fe3+ is 0.02 M and OH- is 0.1 M at 25°C, what is the new equilibrium constant at 35°C assuming the reaction is exothermic and the heat of reaction is -20 kJ/mol?
