The oxidations of pentan‐1‐ol with 12 dichromates, fluorochromates, chlorochromates and bromochromate of heterocyclic bases in acidic medium exhibit identical kinetic behavior; first order each with respect to the chromium(VI) reagents and alcohol, and are acid catalyzed. The Arrhenius plots show two common points of intersection, one by the three quinolinium complexes and the other by the rest, suggesting the involvement of the quinolinium moiety in the transition state to be different from that of the other heterocyclic bases.

The oxidations of diethyl sulfide by potassium dichromate, pyridinium dichromate, quinolinium dichromate, imidazolium dichromate, nicotinium dichromate, isonicotinium dichromate, pyridinium fluorochromate, quinolinium fluorochromate, imidazolium fluorochromate, pyridinium chlorochromate, quinolinium chlorochromate, and pyridinium bromochromate follow identical kinetic orders-first-order each with respect to the chromium(VI) reagents, sulfide and hydrogen ion, and moderately inhibited by manganese(II) ion. The energy of activation varies linearly with the logarithm of frequency factor and so does the enthalpy of activation with the entropy of activation. Also, the activation free energies do not differ significantly. The dichromates and halochromates of heterocyclic bases oxidize diethyl sulfide via a common mechanism. C

The reaction constants for the oxidations of primary aliphatic alcohols with 12 dichromates and halochromates of heterocyclic bases do not differ significantly indicating operation of a common mechanism. C

The oxidation of benzyl alcohol by dichromate and seven chromium(VI) complexes in aqueous acetic acid in the presence of perchloric acid is first order each in the oxidants, the alcohol and the mineral acid. The oxidation conforms to the isokinetic and Exner relationships and follows a common mechanism.

Stress is believed to be a state of the mind as well as the body, created by certain biochemical reactions in the human body as well as psychological responses to situations, and is reflected by a sense of anxiety, tension and depression and is caused by such demands by the environmental forces or internal forces that cannot be met by the resources available to the person. The greater the gap between the demands and the resources, the greater is the degree of stress. Some of the individual strategies for coping with stress include: readjustment of life goals, support from family and friends, planning certain events of life in advance and keeping the body in good physiological shape by proper diet, exercise, yoga, meditation and biofeedback. Some of the organizational strategies for coping with stress include organized health maintenance facilities as a part of the organizational life, matching of employees qualifications with job requirements, job enrichment and job work redesigns, equitable performance appraisal and reward systems, participation in organizational decision making and building team spirit in the sense that there should be no interpersonal conflict within the group. All these strategies or a combination thereof should be applied to make the work environment less stressful to a level which is positive and challenging.
