What is the value of for this aqueous reaction at 298 k? a b↽−−⇀c dδ°=20. 46 kj/mol
sineoko [7]

The value for this aqueous reaction at 298 k? a b↽−−⇀c dδ°=20. 46 KJ/mol is 9.91 mol. in equilibrium

<h3>What is an aqueous reaction in equilibrium?</h3>

When a chemical reaction happens at the liquid state and the formation of reactant and product is the same then the reaction is known as an aqueous reaction in equilibrium denoted by K.

δG = − R T ln

          R = universal gas constant 8.313

          δG= 20. 46 kj/mol

           T =  298 k or 24.4 in celcius.

substituting the value in the equation.

20. 46 kj/mol = 8.313 × 24.4 in celcius × K

K =  8.313 × 24.4 in celcius / 20. 46 kj/mo

k = 9.91 mol .

Therefore, The value of this aqueous reaction at 298 k? a b↽−−⇀c dδ°=20. 46 KJ/mol is 9.91 mol. in equilibrium

Draw the ester formed by the reaction of heptanoic acid and ethanol.
wariber [46]

Answer:

Ethyl heptanoate (see the attached image for the structure).

Explanation:

  • The reaction of heptanoic acid and ethanol will result ethyl heptanoate ester.
  • Ethyl heptanoate is the ester resulting from the condensation of heptanoic acid and ethanol. It is used in the flavor industry because of its odor that is similar to grape.
  • Kindly, see the attached image of the structure and the reaction.

What column do these go into physical or chemical property ??
RSB [31]

Answer:

Explanation:

Chemical properties:

These are the properties which involve the chemical reaction.

For example:

Combustion, flammability, toxicity, enthalpy of formation etc are chemical properties.

Reaction with oxygen ( chemical property)

Conduction of heat ( chemical property)

Not flammable (chemical property)

Physical properties:

The property which not involve any chemical reaction it only involve the physical appearance of substance.

For example:

Density, odor, color, texture etc.

Smooth texture (physical property)

Reddish color ( chemical property)

Sink in water ( chemical property)

6. If concentrations measured in moles per liter, and time in seconds, what are the units of the rate constant for (a) a first o
kaheart [24]

Answer:

(a) a first order reaction = s^-1.

(b) a second-order reaction = L(mol·s)

(c) a third-order reaction = s⁻¹M⁻²

Explanation:

Okay, this question is a question that has to do with kinetics that is how reaction occurs.

So, the RATE LAW is one of the concept that is being used in determining conditions of chemical reactions. The relationship between the the reactants molarity and the reaction rate is known as rate law. That is to say;

Rate law = K × Molarity.

So, In this question we are given that the concentrations measured in moles per liter, and time in seconds.

The FIRST ORDER REACTION has its unit for rate constant as per seconds(s^-1).

That is from; Rate law = k

Molarity/s = k × Molarity.

k = s^-1

(b) a second-order reaction;

Rate law= k × (molarity)^2.

Molarity/s = k × (Molarity)^2.

k = L(mol·s)

(c) A third-order reaction = s⁻¹M⁻²

Same thing applies.
