Answer:

402 kJ

Explanation:

Because the energy of the reaction is positive, the reaction is endothermic. This means energy is a reactant.

You can determine how much energy/heat is absorbed using the balanced chemical equation. You can convert the moles A using the ratio composed of the coefficient in front of A and the energy required for each reaction.

2A + B + 309 kJ ⇌ 2C + 2D

2.60 moles A 309 kJ
---------------------- x -------------------- = 402 kJ
2 moles A

In principle, the equilibrium in the dehydration of an alcohol could be shifted to the right be removal of water. Why is this ta

Trava [24]

Answer:

See explanation

Explanation:

In this case, we have to remember that if we want to remove water from the reaction vessel we have to heat the vessel. So, we can convert the liquid water into gas water and we can remove it from the vessel. In this case, the products of dehydration for both molecules are (E)-4-methylpent-2-ene and cyclohexene with boiling points of 59.2 ºC and 89 ºC respectively. The boiling point of water is 100 ºC, therefore if we heat the vessel the products and water would leave the system, and the products would be lost.
