Please explain the two cases by using chemical kinetics,
NO NEED to answer the first 9 marks. JUST EXPLAIN THE THE TWO
CASES !!! Thank you.
5. Use chemical kinetics equations to derive the relations between half-life and the initial concentration of the reactant for zero, first and second order reactions (9 points). And then use the relations derived above to explain: 1) Why you tend to be more anxious seeing a long line ahead of you at the customs (e.g., at Luo Woo checkpoint). (3 pts) 2) Why single people tend to gravitate towards major metropolitan centers (like Hong Kong) to increase their opportunities of finding a spouse. (3 pts) (total 15 points)
