Question 1

Substance A decomposes by a first-order reaction. Starting initially with [A] = 2.00 M, after 150 min [A] = 0.50 M. For this reaction what is t1/2?
◦ 150 min
◦ 37.5 min
◦ 75.0 min
◦ 15.0 min
◦ 300 min

Question 2

The aquation of tris (1,10-phenanthroline)iron(II) in acid solution takes place according to the equation:

Fe(phen)32+ + 3 H3O+ + 3 H2O → Fe(H2O)62+ + 3 phenH+.

If the activation energy, Ea, is 126 kJ mol-1 and the rate constant at 30 °C is 9.8 × 10-3 min-1, what is the rate constant at 35 °C?
◦ 4.4 × 10-3 min-1
◦ 2.2 × 10-2 min-1
◦ 4.5 × 101 min-1
◦ 2.3 × 102 min-1
