(a) The decomposition of HI(g) to give H2(g ) and 12(g) is 2nd order with a rate constant, k equal to 30 M min. at 443°C. How long does it take in minutes) for a concentration of 0.010 M of HI (g) to drop to half its value at 443°C? [2 Marks] Answer: t = 3.33 minutes (b) If a temperature increase from 20 °C to 35 °C triples the rate constant for a reaction, what is the value of the activation energy (in kJ/mol) for the reaction? [3 Marks) Answer: Ea = 55.02 kJ/mol
