Chem, help please

Consider the reaction

N2 + 3H2 in equilibrium with 2 NH3 .

At 25°C Ho = -92.22 kJ and So = -198.53 J/K. Using this information, calculate the equilibrium constant for the reaction at 226°C. (R = 8.314 J/K)

Enter your answer using TWO significant figures. You may use scientific notation with an "e" if necessary (e.g., 1.2e34).
