Write down the phenomenon that are generally accompanied with Chemical changes. |
| Answer» <html><body><p>The phenomenon catalysis can be understood as an acceleration of a thermodynamically feasible reaction through the presence of a substance, the catalyst, which itself is neither essentially altered nor consumed by this chemical action. The overall rate of the reaction sequence is obtained <a href="https://interviewquestions.tuteehub.com/tag/assuming-1986865" style="font-weight:bold;" target="_blank" title="Click to know more about ASSUMING">ASSUMING</a> steady-state, which means that both reactions proceed at the same rate, and the decomposition of the transition state complex is rate determining. The features that determine predominantly, the suitability of catalysts in chemical reactions <a href="https://interviewquestions.tuteehub.com/tag/includes-1039937" style="font-weight:bold;" target="_blank" title="Click to know more about INCLUDES">INCLUDES</a> activity, selectivity, and <a href="https://interviewquestions.tuteehub.com/tag/stability-651358" style="font-weight:bold;" target="_blank" title="Click to know more about STABILITY">STABILITY</a>. The activity indicates the reactivity of <a href="https://interviewquestions.tuteehub.com/tag/catalytic-910648" style="font-weight:bold;" target="_blank" title="Click to know more about CATALYTIC">CATALYTIC</a> systems, the rate at which reactants are transformed into products, the selectivity is a measure of the ability of a catalyst to <a href="https://interviewquestions.tuteehub.com/tag/preferentially-7707027" style="font-weight:bold;" target="_blank" title="Click to know more about PREFERENTIALLY">PREFERENTIALLY</a> catalyze one of a number of possible reactions and the stability indicates how long a catalyst will be able to fulfill its action</p></body></html> | |
