half time of zero order reaction in kinetic chemistry

Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The volume of the reaction vessel is kept cons..

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, ..

Reaction Quotient and the Equilibrium Constant - The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The valu..

All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in a..

In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated with the help of followi..

Radioactive Dating - All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in ..

Isolation Method - For reactions where many reactants are involved, the order of the reaction is determined by the method of isolation. This was developed by Ostwald. In this method, the concentrations of all the reactants except one are taken in excess. For e.g., in t..

. Transition state is supposed to be in equilibrium with the reactants. It also has a very short life. That is why, when it was proposed in the 1930s, it was not possible to study the transition state with the techniques available then. With the help of laser pulses of femtosecond to picoseconds le..

o = Amount of U-238 isotope originally present in a small quantity of the rock or mineral at the time the rock was formed. N = Amount of U-238 still left undecayed after the lapse of time t which represents the age of the rock. k = the decay constant of U-238. We can determine..
