Ayuda plis :(Cuando una reacción es de orden cero: ¿porqué se llama orden cero?​

Chemistry
1 answer:
KiRa [710]3 years ago

Answer:

Revisa la explación detallada, por favor.

Explanation:

¡Hola!

En este caso, teniendo en mente la definición de ley de velocidad, es posible recordar que esta tiene la forma genérica:

r=k[A]^m

En donde k es la constante de velocidad, [A] la concentration de cualquier especie A en la reacción y m el orden the reacción. Ahora, hay tres órdenes de reacción, cero, primer, y segundo orden, y esto pasa cuando m=0, m=1 y m=2 respectivamente. Por lo tanto, si la reacción es de orden cero, la rapidez de reacción resulta igual a la constante de velocidad dado que la concentración estaría elevada a la cero y por consiguiente siempre tendrá valor de 1, por lo que la concentración no afecta la velocidad de reacción. Esto anterior se expresa como:

r=k[A]^0\\\\r=k

¡Saludos!

Which two subatomic particles do you add together to determine the atomic mass or mass # of the atom?
raketka [301]

Answer:

Protons and Neutrons

Explanation:

The sum of number of protons and the number of neutrons is equal to the mass of an element. Mathematically, it can be given as :

M = P + N

Also, the atomic mass can be calculated by the sum of the element's isotopes as isotopes have slightly different mass numbers.

Hence, protons and neutrons add together to determine the atomic mass.

We have air (21% O2 and 79% N2) at 23 bar and 30 C. 4. What is the ideal molar volume (m^3/kmol)? a. b. What is the Z factor? Wh
k0ka [10]

Answer:

The  ideal molar volume is  \frac{V}{n}  =V_z=  0.001095 \ m^3/mol  

The  Z factor is  Z = 0.09997

The  real molar volume is \frac{V_r}{n} = V_k=   0.0001095\ \frac{m^3}{mol}

Explanation:

From the question we are told that

    The pressure is  P  = 23 \ bar =  23 *10^5 Pa

      The temperature is  T  =  30 ^ oC  = 303 \ K

According to the ideal gas equation we have that

          PV  =  nRT

=>      \frac{V}{n}=V_z= \frac{RT}{P}

Where  \frac{V}{n } is the molar volume  and  R is the gas constant with value

            R  =  8.314 \ m^3 \cdot Pa \cdot K^{-1}\cdot mol^{-1}

substituting values

            \frac{V}{n}  =V_z=  \frac{ 8.314 *  303}{23 *10^{5}}

             \frac{V}{n}  =V_z=  0.001095 \ m^3/mol            

The  compressibility factor of the gas is mathematically represented  as

            Z = \frac{P *  V_z}{RT}

substituting values        

          Z = \frac{23 *10^{5} *   0.001095}{8.314 * 303}

          Z = 0.09997

Now the real molar volume is evaluated as

         \frac{V_r}{n} = V_k=  \frac{Z *  RT }{P}

substituting values

             \frac{V_r}{n} = V_k=   \frac{0.09997 *  8.314 *  303}{23 *10^{5}}

             \frac{V_r}{n} = V_k=   0.0001095\ \frac{m^3}{mol}

The diameter of a hydrogen atom is approximately 1.06 ✕ 10−10 m, as defined by the diameter of the spherical electron cloud arou
mylen [45]

Answer:

a) 10.0 mm

b) 8.7 x 10¹³ times

Explanation:

Atom diameter = 1.06 x 10⁻¹⁰ m  ________________ 100%

Nucleus diameter = 2.40 x 10⁻¹⁵ m ______________   x

x = 2.26 x 10⁻³ %

The nucleus diameter is equivalent to 2.26 x 10⁻³ % of the total atom size.

a) The Empire State Building model:

1 ft = 304.8 mm

1454 ft = 443179.2 mm

443179.2 mm______ 100%

        y           ______   2.26 x 10⁻³ %

              y = 10.0 mm

In this model,  the diameter of the nucleus would be 10.0 mm.

b) Sphere volume: V =(4 · π · r³ )/3

V atom = (4 . π .( 0.53x10⁻¹⁰)³ )/3

V atom = 6.2 x 10⁻³¹ m³

V nucleus = (4 . π .( 1.2x10⁻¹⁵)³ )/3

V nucleus = 7.2 x 10⁻⁴⁵ m³

V atom / V nucleus = 6.2 x 10⁻³¹ m³ / 7.2 x 10⁻⁴⁵ m³

V atom / V nucleus = 8.7 x 10¹³

The atom is  times 8.7 x 10¹³ larger in volume than its nucleus.
