Define Acid dissociation constant constant

Chemistry
1 answer:
stiks02 [169]3 years ago
6 0

Answer:

An acid dissociation constant, K a, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction ↽ − − ⇀ − + + known as dissociation in the context of acid–base reactions.

What would happen to the rate of a reaction with rate law rate = k [NO]^2[H2] if
Ede4ka [16]

The rate of a reaction would be one-fourth.

<h3>Further explanation</h3>

Given

Rate law-r₁ = k [NO]²[H2]

Required

The rate of a reaction

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

Can be formulated:  

Reaction: aA ---> bB  

\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}

or  

\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}

The concentration of NO were halved, so the rate :

\tt r_2=k[\dfrac{1}{2}No]^2[H_2]\\\\r_2=\dfrac{1}{4}k.[No]^2[H_2]\\\\r_2=\dfrac{1}{4}r_1

When two fluorine atoms bond together in F2, what type of covalent bond do they form?
makvit [3.9K]

When two  fluorine  atoms  bond  together  in f2  the  type of covalent  bond   do they  form is non-polar covalent   bond.


  Explanation

They are  two type of covalent bond.  that is non polar covalent bond and  polar covalent  bond.


Non polar  covalent  bond  is formed  when atoms share  a pair  of electrons  with each other  equally.

polar covalent  bond is bond formed when  atoms share  a pair   electrons unequally.


 F2  is a non polar  since  it is made  up of two  same atoms   which  has  the  same electronegativity, therefore equal number of electrons exist  in the  orbital overlap.

Which processes result in the realese of carbon
Zanzabum

Answer:

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combines with oxygen in the air to form carbon dioxide and water vapor.
