Question

Write down the phenomenon that are generally accompanied with Chemical
changes.

Answer 1

Answer:

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 assuming 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 includes activity, selectivity, and stability. The activity indicates the reactivity of catalytic systems, the rate at which reactants are transformed into products, the selectivity is a measure of the ability of a catalyst to preferentially catalyze one of a number of possible reactions and the stability indicates how long a catalyst will be able to fulfill its action
