EDTA is a synthetic amino acid and is a chelating agent. They are are capable of forming bonds with heavy metals in order to form very complex structures wherein the body could dispose easily in through the urine. It is used in removing lead, mercury, iron, aluminum and many other metals.<span />

I was wondering what the answer for this question would be ?

Answer:

C. H2O is the base and H3O+ is the conjugate acid

Explanation:

According to Bronsted-Lowry acid-base theory, an acid is a substance that loses an hydrogen ion or proton (H+) while a base is a substance that gains an hydrogen ion (H+) or proton. Furthermore, this theory states that, the molecule formed when an acid donates its proton is called the CONJUGATE BASE, while the molecule formed when the base accepts proton is called CONJUGATE ACID.

In this question, the following equation is given:

NH4+(aq) + H2O(aq) ⇌NH3(aq) + H3O+ (aq)

Water (H2O) is the base in this equation because according to Bronsted-Lowry acid-base theory, it accepts an hydrogen ion (H+) while hydroxonium ion (H3O+) is the conjugate acid.

Use the exponential term in the Arrhenius equation to explain how temperature affects reaction rate.
WINSTONCH [101]

The Arrhenius equation describes the relation between the rate of reaction and temperature for many physical and chemical reactions

It is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature.

The Arrhenius equation,

k = zpe^{\frac{- Ea}{RT} }, where

k is the rate constant,

z is the collision factor,

p is the steric factor,

Ea is the activation energy,

R = 8.3245 \frac{J}{mol. K} is the ideal gas constant, and,

T is the temperature.

The activation energy by definition, is the minimum energy (or threshold energy) required for two particles of reactants upon collision to form products.

The Arrhenius equation could also be written as:

⇒ k = Ae\frac{-Ea}{RT}, where

⇒ A = zp, the Arrhenius factor.

Taking the neutral logarithm of both parties, we get:

⇒ In k = \frac{-Ea}{RT}\frac{(1)}{(T)} + In A,

Assuming that, A is independent of temperature, when T is increased, the equilibrium constant k will also increase and therefore, the rate of the reaction will also increase.
