half life of a reaction

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2..

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction is given as In general, for a r..

Half-life is the time period during which half the number of atoms present initially in the sample of radioactive element decays. When t = T ; N = N o /2 The radioactive decay of radium is 1,620 years. The time required to reduce a given quantity of that element by ..

Half-Life Period - The time required for the decay of the radioactive element to one half of its original amount is called Half-Life Period . It is denoted by t 1 / 2 . Putting these values in equation (iii), we g..

This energy further increases the temperature and pressure inside the star. A star has a core and an outer shell. The internal pressure created due to the energy released during fusion stops the core from collapsing. The star is in a delicate equilibrium under two opposing forces - the gravitation..

In these half-reactions, the number of electrons lost and gained are not equal. These can be made equal by multiplying the above reaction at the cathode by..

Corrosion :- Many metals are chemically active elements and get easily affected by substances like moisture, air, acids, etc. One must have observed iron articles that are shiny when new, but get coated with a reddish brown powder when left for some time. This process is commonly known as ru..

) whereas artificial radioactivity can be induced in elements with low atomic numbers. iii) Artificial radioactive isotopes generally have short half-life periods. iv) They are very rarely found in nature because they decay off as soon as they are formed due to short half-life p..

A galvanic cell consists of two electrodes dipping into the same or two different electrolytes. No reaction takes place until a conducting wire joins the two electrodes. Once, a chemical reaction takes place at each electrode, electron transfer takes place. The electron-tr..
