Answer:
The catalyzed reaction will take time of .
Explanation:
According to the Arrhenius equation,
The expression used with catalyst and without catalyst is,
where,
= rate of reaction with catalyst
= rate of reaction without catalyst
= activation energy with catalyst = 59.0 kJ/mol = 59000 J/mol
= activation energy without catalyst = 184 kJ/mol = 184000 J/mol
R = gas constant
T = temperature =
Now put all the given values in this formula, we get:
The reaction enhances by when catalyst is present.
Time taken by reaction without catalyzed = 3900 years
Time taken by reaction with catalyzed = x
The catalyzed reaction will take time of .
Answer:
crystal structure
Explanation:
A crystal structure is an ordered arrangement of atoms,ions or molecules in a regular repeating pattern,it is a form of solid state of matter and differs from liquid and gaseous states of matte in which the atoms or molecules are random or haphazard.
Answer:
Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points.
Explanation:
Answer:
When the metal reacts with hot, concentrated sulphuric acid, the products of the reaction are copper (II) sulphate, sulphur dioxide and water. Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O. This is a typical redox reaction in which the acid is reduced to SO2, but no hydrogen is produced here
Unsaturated organic compounds with a carbon-to-carbon double bond and alkynes with a carbon-to-carbon triple bond, as well as aldehydes and ketones with a carbon-to-oxygen double bond, undergo addition reactions.
