The order m was found by the method of initial rates to be ~1. The observed rate constant found at 25\u00B0C, 4.17\u00D710-5s-1, was able to be compared to the literature value7of 1.72\u00D710-6s-1. This inconsistency is attributed to differences in ionic strength. The activation energy, Ea, was found to be 45 kJ/mol and the frequency factor, A, was found to be 3.8\u00D7103s-1. An enthalpy, \u0394H, of 94 kJ/mol matched appropriately with the accepted value of 93 kJ/mol. Additionally, the pKaof coordinated water in [Co(NH3)5(H2O)]Cl3could be determined using titration and spectroscopy. The titrimetric method yielded a pKaof 5.66, while the two spectroscopic methods gave pKa\u2019s of 5.96 and 5.77. An average pKaof 5.80 was determined, making the coordinated water ~10 billion times more acidic than uncoordinated water. Lastly, the kinetics of the decomposition of [Co(NH3)4(CO3)]NO3were studied.The reaction follows a rate law \uD835\uDC5F\uD835\uDC4E\uD835\uDC61\uD835\uDC52=\uD835\uDC58\u2032[(\uD835\uDC41\uD835\uDC3B3)4\uD835\uDC36\uD835\uDC5C\uD835\uDC36\uD835\uDC423\u002B]\uD835\uDC5A, wherek\u2019 = [H\u002B]nat a constant pH. The reaction was studied at three different pH\u2019s and the k\u2019 value determined for each. It was concluded that both m and n equal one, giving the reaction a second order rate law." ] } }, { "label": { "en": [ "Publication Date" ] }, "value": { "none": [ "2016 January 25" ] } }, { "label": { "en": [ "Hierarchical Spatial" ] }, "value": { "none": [ "New Jersey -- Edison" ] } }, { "label": { "en": [ "Holding Location" ] }, "value": { "none": [ "Middlesex County College Institution" ] } }, { "label": { "en": [ "Permanent Link" ] }, "value": { "none": [ "http://middlesexcc.sobeklibrary.com/AA00002426/00001" ] } }, { "label": { "en": [ "Creator" ] }, "value": { "none": [ "Schneider, Sarah", "Ghosh, Phalguni", "Middlesex College, Department of Natural Sciences" ] } }, { "label": { "en": [ "Publisher" ] }, "value": { "none": [ "Middlesex College" ] } }, { "label": { "en": [ "Place of Publication" ] }, "value": { "none": [ "Edison, NJ" ] } }, { "label": { "en": [ "Type" ] }, "value": { "none": [ "Mixed Material" ] } }, { "label": { "en": [ "Source Institution" ] }, "value": { "none": [ "Middlesex County College Institution" ] } }, { "label": { "en": [ "Subjects / Keywords" ] }, "value": { "none": [ "College students -- poster presentations", "Student Works -- Natural Sciences -- poster presentations", "Chemistry", "Student works -- Natural Sciences -- academic theses", "Middlesex College (Edison, NJ) -- Student works", "Middlesex County College (Edison, NJ)" ] } }, { "label": { "en": [ "Temporal Coverage" ] }, "value": { "none": [ "Academic Year 2015-2016 ( 2015 - 2016 )" ] } }, { "label": { "en": [ "Title" ] }, "value": { "none": [ "Kinetics of Aquation of Pentaamminechlorocobalt(III) and Kinetics of Decomposition of Tetraamminecarbonatocobalt(III) Revisited.
