Chemistry

1 answer:

Answer:

reaction rates increase because reactants move faster, collide more often, and produce more collisions with the required energy of activation.

Explanation:

At higher temperatures, the reactant atoms gain high kinetic energy which decreases the intermolecular forces of attraction between these atoms/molecules.

Hence the rate of collision is very high which decreases the activation energy and products are formed with in a short period of time.

1,4-Pentadiene has a AHhydro = -254 kJ/mol while trans-1,3-pentadiene has a AHhydra = -226 kJ/mol. Explain this difference in he

julsineya [31]

Answer:

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Explanation:

Here, $\Delta H_{hydro}=H(hydrogenated pdt.)-H(diene)$

H(hydrogenated pdt.) is same for both 1,4-pentadiene and 1,3-pentadiene as they both produce pentane after hydrogenation

H(diene) depends on stability of diene.

More stable a diene, lesser will be it's H(diene) value (more neagtive).

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Hence, $\Delta H_{hydro}$ is higher (less negative) for trans-1,3-pentadiene

Zinc and hydrochloric acid react to form zinc chloride and hydrogen gas according to

stealth61 [152]

Explanation:

Mole ratio of Zn to HCl = 1 : 2.

If we use all 2.0mol of Zn, we would need 2.0 * 2 = 4.0mol of HCl. However we only have 3.0mol of HCl.

Therefore HCl is limiting.

What kind of bond is created by a week electrical attraction between polar molecules

Studentka2010 [4]

Answer : The dipole-dipole interaction.

Explanation : The kind of bond that is created by a weak electrical attraction between two polar molecules is dipole-dipole interaction.

The type of force which occurs between the positive end of one molecule and the negative end of another molecule: is dipole-dipole interaction.
