Reaction rate depends on how often molecules come into contact with each other, the way in which they come together, and the amo

unt of energy they have when they come in contact.
Which of the following factors would you expect to affect the way in which molecules affect each other?
A) volume
B) catalysts
C) pressure
D) temperature

The most appropriate answer is D ! temperature !

as when temperature increases KE increases and the collision factor and frequency increases !

I know that the volume wouldn't have much affect because putting the 2 molecules together would cause the volumes density. I believe it would be the catalyst. I'm not completely sure because I haven't taken science in soo long.

Answer:

The enthalpy of reaction for the reaction of chlorine with ozone is -162.5 kJ.

Explanation:

ClO ( g ) + O_3 ( g )\rightarrow Cl ( g ) + 2 O_2 ( g ),\Delta H^o_{1,rxn} =-122.8 kJ..[1]

2 O_3 ( g )\rightarrow 3O_2 ( g ),\Delta H^o_{2,rxn} = -285.3 kJ..[2]

O_3(g) + Cl(g)\rightarrow ClO (g)+O_2(g),\Delta H^o_{3,rxn}=?..[3]

The enthalpy of reaction for the reaction of chlorine with ozone can be calculated by using Hess's law:

[2] - [1] = [3]

\Delta H^o_{3,rxn}=\Delta H^o_{2,rxn}-\Delta H^o_{1,rxn}

=-285.3 kJ-(-122.8 kJ)=162.5 kJ

The enthalpy of reaction for the reaction of chlorine with ozone is -162.5 kJ.

Comare and contrast physical property and chemical property
Nimfa-mama [501]
A physical property is a quality or condition of a substance that can be observed or measured without changing the substance's composition. a chemical property is the ability of a substance to undergo a specific chemical change.

Does the volume of particles affect the behavior of gas
lilavasa [31]

Answer:

Yes, it does, although only physically and not chemically.

Explanation:

If a volume of gas is way spread out, it won't collide with the other gas particles as often, reducing pressure and temperature because they lose kinetic energy to their surroundings when they don't collide.

If it is compressed, it increases temperature and pressure because the gas particles collide with each other and the walls of the container way more often than if they had more space.

Hope this answers your question.

P.S.

Fun fact, gas particles are actually moving at 300-400 meters per second at room temperature, they only slow down to walking speed at very low temperatures, like 10 Kelvin

Which of the following molecules, having a bond with chlorine, contains an ionic bond? Chlorine gas, Calcuim Chloride, Carbon Te
natka813 [3]

Answer: In calcium chloride there is one calcium atom and two chloride atoms attached to it, it has an ionic bond with chlorine and calcium. A bond is said to be an ionic bond if it is formed by the electrostatic attraction between one negatively charged and one positively charged ions. Ions are the atoms which are formed on the gain or loss of electrons to an atom. All the other molecules have covalent bonds, which forms on sharing of electron pairs.
