(a) What is meant by the terms
(i) a global reaction;
(ii) an elementary reaction;
(iii) a reaction mechanism.
(b) Describe the steps required to form a chain reaction and explain why chain reactions are important in combustion.
(c) A reaction is found to be 25 times faster at 400 K than at 300 K. Measurements of the temperature exponent yielded a value of 0.7. Calculate the activation energy of the reaction. How much faster will the reaction be at 1000 K?
