Question

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 and the rate constant at 30C is 9.8 10-3 min-1, what is the rate constant at 35C?
A) 4.4 10-3 min-1
B) 2.2 10-2 min-1
C) 4.5 101 min-1
D) 2.3 102 min-1
