Half-Life of a Reaction
The half-life of a reaction is the time in which the concentration of a reactant is reduced to one half of its initial concentration.
Represented as: t1/2
- For a zero order reaction, rate constant is given by equation.
- For the first order reaction,
Pseudo First-Order Reactions
Reactions which are not truly of the first order but under certain conditions become reactions of the first order.
The concentration of water does not get altered much during the course of the reaction. So, in the rate equation the term [H2O] can be taken as constant.
