Answer:

The correct answer is b. a substance that is a hydrogen ion donor

Explanation:

According to Arrhenius Theory, a base is all that substance that when dissolved releases hydroxyl ions (OH–). The bases are also known as alkalis, because when the hydroxyl groups dissociate and release, the pH of the solutions increases, that is, the solution becomes alkaline. So its pH is greater than 7.

Also, according to this theory, acids are those substances that dissolved in water divide H + together with an anion. In this case the pH is less than 7.

But this theory has the disadvantage of being valid only in an aqueous medium. And it does not consider non-protic acids incapable of releasing hydrogenic ions, nor bases incapable of liberating hydroxylic ions.

<u><em>The correct answer is b. a substance that is a hydrogen ion donor</em></u>

Given the initial rate data for the reaction A + B –––&gt; C, determine the rate expression for the reaction.
umka21 [38]

Answer:

B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]

Explanation:

For the reaction A + B → C

The formula for rate of reaction is:

Δ[C]/Δt = k [A] [B]

As you have [A], [B] and Δ[C]/Δt information you can multiply [A] times [B] and take this value as X and Δ[C]/Δt as Y. The slope of this lineal regression will be k.

Thus, you must obtain:

y = 3,60x10⁻² X

Thus, rate of reaction is:

B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]

I hope it helps!
