1. The thermal decomposition of hydrogen iodide to hydrogen and iodine is conducted in a batch reactor. The following data are given

T, °C	508	427	393	356	283
k, cm3/mol/s	0.1059	0.00310	0.000588	80.9 x 10 -6	0.942 x 10 -6

Show that the temperature dependency of rate equation follows Arrhenius equation. Find the activation energy and frequency factor.

2. The following data were obtained on the reaction 2 A -> B in a batch reactor

Time, s	0	5	10	15	20
[A], mol L-1	0.100	0.0141	0.0078	0.0053	0.004

Using a suitable plot, show that the reaction is second order. Find the rate constant.
