AN OUTLINE OF KINETICS VERSUS THERMODYNAMICS CHEMISTRY
Abstract: Nearly all chemical reactions has a kinetic and a thermodynamic feature. The terms ‘kinetic’ and ‘thermodynamic’ though inter-related are two diverse aspects of a chemical reaction. This paper represents an outline of the underlying relationships between the two through application to chemical reactions and an example from natural processes. A required condition for thermodynamic control is reversibility or a mechanism allowing the equilibration between products. In this manner, the thermodynamically …

Importance of the Laws of Thermodynamics in the Field of Chemical Sciences
Abstract: The Laws of Thermodynamics are important because they control interactions of everything in the universe - regardless of scale. These rules stretch across every form of science known to humankind. Classical physics is, from a certain perspective, entirely based on Newton's Laws of motion. The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law …

Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …
