2. Tris(1,10-phenanthroline)iron(II) reacts in an acidic solution according to the equation:
Fe(phen)32+ + 3H3O+ + 3 H2O --> Fe(H2O)62+ + 3phenH+
If the activation energy, is 124 kJ/mol and the rate constant at 29 degrees C is 0.0091 min^1-1, what is the rate constant at 52 degrees C? Units: min^-1

What I did: ln(0.0091/k2)=-12400/8.31(1/325.15-1/302... I had converted kj to j, and degrees C to K
ln(0.0091/k2)=.3493

E^.3494=0.0091/k2
k2=0.0091/1.4181
k2=.0064

Correct Answer: 0.29985

Where did I go wrong?
