Answer:
An increase in temperature indicates that the molecules of gas speed up.
Explanation:
The molecular kinetic theory states that the average kinetic energy of gas particles (molecules) is proportional to the absolute (Kelvin) temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
Therefore, as the temperature increases so the kinetic energy increases.
It is also known that the kinetic energy is proportional to the squared speed of the particles, therefore the higher the kinetic energy the average speed of the molecules:
- higher temperature → higher kinetic energy → higher average speed
Answer:
2.5 moles of N₂ and 7.5 moles of H₂ entered the reaction
Explanation:
In reaction:
N₂(g) + 3 H₂(g) → 2 NH₃(g)
You can see that the stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) requires the following amounts of reagents and are produced:
- N₂: 1 mole
- H₂: 3 moles
- NH₃: 2 moles
The following three rules can apply:
- If 2 moles of NH₃ are produced from 1 mole of N₂ by stoichiometry of the reaction, 5 moles of NH₃ from how many moles of N₂ are produced?

moles of N₂= 2.5
- If 2 moles of NH₃ are produced from 3 moles of H₂ by stoichiometry of the reaction, 5 moles of NH₃ from how many moles of H₂ are produced?

moles of H₂= 7.5
<u><em>2.5 moles of N₂ and 7.5 moles of H₂ entered the reaction</em></u>
