The half-life gets longer as the initial concentration increases in zero-order reaction.
The amount of time it takes for the concentration of a given reactant to reach 50% of its initial concentration is known as the half-life of a chemical reaction (i.e. the time taken for the reactant concentration to reach half of its initial value).
For zero order reaction:
The half-life is given as:
![t_{1/2}=\frac{[A]_{0}}{2k}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B%5BA%5D_%7B0%7D%7D%7B2k%7D)
where k is the rate constant of the reaction and ![[A]_{0}](https://tex.z-dn.net/?f=%5BA%5D_%7B0%7D)
is the initial concentration.
As we can see that the half-life is directly proportional to the initial concentration. Therefore, when the initial concentration increases the half-life gets longer.
For the first-order reaction,
The half-life is given as:
A first-order reaction's half-life is independent of the initial concentration.
For a second-order reaction,
The half-life is:
![t_{\frac{1}{2} }=\frac{1}{k[A]_{0}}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%5Cfrac%7B1%7D%7Bk%5BA%5D_%7B0%7D%7D)
The initial concentration is inversely proportional to the half-life, so when the initial concentration increases the half-life will get shorter.

Answer:
See explanation below
Explanation:
In picture 1 attached, we have the starting structure. In picture 2, you have the answer for this.
Basically this is an acid base reaction to promove then, a condensation of the molecule.
In the first step, the carbonile substract a H atom from the HCl. Then, by resonance the OH+, pass the charge to the carbon, which is tertiary and can be easily stabilized. Now, after this, the Chlorine substract an Hydrogen to get a double bond on the carbon with the charge, and this be stable. Now, a second molecule of benzaldehyde reacts with this, so we can have a condensation product.
See picture 2 for complete mechanism.
Answer:
1) Dispersion forces: It is a type of force which is present between atoms and molecules. It is a weakest intermolecular force that occurs between atoms. It is also called induced dipole-induced dipole attraction.
2. Dipole-dipole: It is a type of attractive force which is present between the negative end of one molecule with the positive end of another molecule. This type of attractive force occurs between polar molecules.
3) Hydrogen bond: It is a type of electromagnetic force which is present between hydrogen and high electronegative atoms such as nitrogen and oxygen etc.
<span>Answer:
Glass has a much higher specific heat than styrofoam so more of the energy produced will go into heating the glass. This quantity of heat will be lost (unaccounted for) hence the delta t in the calculation will be too small and the heat of neutralization will be lower.</span>
