What is the order of reaction if its half-life is independent of initial concentration of reactants?
Notice that, for first-order reactions, the half-life is independent of the initial concentration of reactant, which is a unique aspect to first-order reactions.
What is the order of a reaction with a half-life that is directly proportional to initial concentration?
zero-order reaction
Therefore, for a zero-order reaction, half-life and initial concentration are directly proportional. As initial concentration increases, the half-life for the reaction gets longer and longer.
How is the half-life of a first order reaction affected by the initial concentration of the reactant?
First-Order Kinetics Equation 2.4. 4 shows that for first-order reactions, the half-life depends solely on the reaction rate constant, k. Another way to see it is that the half life of a first order reaction is independent of its initial concentration.
How do you find the order of a half-life reaction?
Another method for determining the order of a reaction is to examine the behavior of the half-life as the reaction progresses. The half-life can be defined as the time it takes for the concentration of a reactant to fall to half of its original value….11.8: The Method of Half-Lives.

What is half-life of first order process?
The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t1/2 = 0.693/k. Radioactive decay reactions are first-order reactions. The rate of decay, or activity, of a sample of a radioactive substance is the decrease in the number of radioactive nuclei per unit time.
How do you find the order of a reaction using half-life?
Another method for determining the order of a reaction is to examine the behavior of the half-life as the reaction progresses. The half-life can be defined as the time it takes for the concentration of a reactant to fall to half of its original value….11.8: The Method of Half-Lives.

What is the half-life of first-order reaction?
What is the order of a reaction?
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant. Thus, for a first-order reaction, the rate is dependent on the concentration of a single species. The order of reaction is an experimentally determined parameter and can take on a fractional value.
