Reaction rate, the speed at which a chemical reaction proceeds, it is often expressed in terms of either concentration (amount per unit volume) of a product that is formed in a unit of tine.
1 of 9
Inital rate of reaction
The initial rate of a reaction is the instantaneous rate at the start of the reaction (i.e., when t = 0).
2 of 9
Order of reaction
a number that relates to the rate of chemical reaction with the concentration of reacting substances.
3 of 9
Rate Constant
a coeffecient of proportionality relating the rate of a chemical reaction at a given temperature to the concentartion of reactants or to the product of the concentration of reactants
4 of 9
Half Life
a substance that undergoes exponential decay, decays by the same ratio at equal intervals of time.
5 of 9
Reaction mechanism
A step by step sequence of elementary reaction by which overall chemical change occurs.
6 of 9
Rate determining step
RDS is the slowest step in a chemical reaction that determines the speed (rate) at which the overall reaction proceeds.
7 of 9
Intermediate
A reaction intermediate is a molecular entity that is formed from the reactants.
8 of 9
Catalyst
A catalyst is a substance that speeds up a chemical reaction but is not consumed by the reaction itself
