The decomposition of NOCl, 2NOCl → 2NO + Cl2, has k = 9.3×10-5 L mol-1s-1 at 100 °C and k = 1.0×10-3 L mol-1s-1 at 130°C. (a) What is Ea for this reaction in kJ/mol? (b) Use the data at 373 K to calculate the frequency factor, A. (c) What is the rate constant at 473 K? Enter your answer in scientific notation.
