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 30°c is 9.8 × 10-3 min-1, what is the rate constant at 35°c? 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 30°c is 9.8 × 10-3 min-1, what is the rate constant at 35°c? 4.4 × 10-3 min-1 4.5 × 101 min-1 2.3 × 102 min-1 2.2 × 10-2 min-1
