Answer : If you add catalyst to a reaction mixture it would increase its rate of reaction to certain extent after sometime the reactant molecules will start regenerating the catalyst molecule again. There will be one moment where reactant molecule will not require any more catalyst and on their own they will do the reaction. The main function of catalyst is to lower the activation energy of the reaction irrespective of decomposition or generation of any product.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Thus the rate for the decomposition of hydrogen peroxide increases on addition of catalyst by lowering the activation energy.
The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. The electrons occupying the orbitals of varying energy levels naturally falls towards the lowest energy state or ground state.
Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.
The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:
A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.
Examples include carbonated water (i.e. soda water); honey; sugar syrup (used in confectionery); supersaturated drug delivery systems. "SDDS"; and sodium acetate solutions prepared from 160 g NaOAc and 30 mL water.
