Answer:
I just did the assignment it's "decreases"
Explanation:
If you guys came from Ed-genuity (i'm writing it like that because apperantly that is a swear word?) That means the next questions are "As you move from left to right across the periodic table, electronegativity..." and "As you move from top to bottom within a group, the first ionization energy...".
for electronegativity, it's increases and for ionization energy it's decreases. Hope this helps!
Answer: Option c. Solution A has a lower boiling point than solution B
Explanation:
For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.
For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds
Therefore, solution A will have a lower boiling point than solution B
Answer:
False.
Explanation:
Activation energy ΔGₐ is only directly affected by the shape of the reaction coordinate curve, and is a function of kinetics.
Activation energy ΔGₐ is the minimum amount of energy needed to overcome the process of the reactant into the transition state, and finally the product. Reaction coordinate diagrams are purely based on potential energy of the molecules (electronic structure).
The <em>rate</em> at which the reaction will occur may change due to high temps, but not the actual ΔGₐ. To better understand, look at the Arrhenius equation. Ea (activation energy) is a constant, and is not affected by temperature changes. The rate constant k is only affected by temperature change.
