  2. Activated complex - Wikipedia

    en.wikipedia.org/wiki/Activated_complex

    Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...

  3. Eyring equation - Wikipedia

    en.wikipedia.org/wiki/Eyring_equation

    The equation follows from the transition state theory, also known as activated-complex theory. If one assumes a constant enthalpy of activation and constant entropy of activation, the Eyring equation is similar to the empirical Arrhenius equation , despite the Arrhenius equation being empirical and the Eyring equation based on statistical ...

  4. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    This theory was developed simultaneously in 1935 by Henry Eyring, then at Princeton University, and by Meredith Gwynne Evans and Michael Polanyi of the University of Manchester. [3] [4] [5] TST is also referred to as "activated-complex theory", "absolute-rate theory", and "theory of absolute reaction rates". [6]

    en.wikipedia.org/wiki/Ralph_D._Stacey

    Ralph Douglas Stacey (October 1948 – September 4 2021) was a British organizational theorist and Professor of Management at Hertfordshire Business School, University of Hertfordshire, in the UK and one of the pioneers of enquiring into the implications of the natural sciences of complexity for understanding human organisations and their management.

  6. Entropy of activation - Wikipedia

    en.wikipedia.org/wiki/Entropy_of_activation

    In chemical kinetics, the entropy of activation of a reaction is one of the two parameters (along with the enthalpy of activation) that are typically obtained from the temperature dependence of a reaction rate constant, when these data are analyzed using the Eyring equation of the transition state theory. The standard entropy of activation is ...

  7. Complexity theory and organizations - Wikipedia

    en.wikipedia.org/wiki/Complexity_theory_and...

    Complexity theory emphasizes interactions and the accompanying feedback loops that constantly change systems. While it proposes that systems are unpredictable, they are also constrained by order-generating rules. [6]: 74 Complexity theory has been used in the fields of strategic management and organizational studies.

  8. Theory U - Wikipedia

    en.wikipedia.org/wiki/Theory_U

    The U Process of Co-sensing and Co-creating — Presencing. Theory U is a change management method and the title of a book by Otto Scharmer. [1] Scharmer with colleagues at MIT conducted 150 interviews with entrepreneurs and innovators in science, business, and society and then extended the basic principles into a theory of learning and management, which he calls Theory U. [1] The principles ...

  9. Organization development - Wikipedia

    en.wikipedia.org/wiki/Organization_development

    Using theory and methods drawn from such behavioral sciences as industrial/organizational psychology, industrial sociology, communication, cultural anthropology, administrative theory, organizational behavior, economics, and political science, the change agent's main function is to help the organization define and solve its own problems. The ...
