Answer:

The best option is "Heat is transferred by the interaction of moving particles."

Explanation:

The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases.

Kinetic theory of heat is a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.

Heat and temperature are related to each other, but are different concepts.

1. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.

2. Temperature does not depend on the size or type of object.

Also heat can be transferred but temperature can't be transferred.

For the reaction below, an analysis of an equilibrium mixture isperformed at a certain temperature.

DerKrebs [107]

Answer:

k = 3.2 x 10¹¹

Explanation:

The equilbrium taking place is:

N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)

And the expression for the equilbrium constant k is

k = [NCl₃]² / ( [N₂] * [Cl₂]³)

We are given all the required data from the problem, so now we solve for k:

k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )

k = 3.2 x 10¹¹

For the reaction A +B+ C D E, the initial reaction rate was measured for various initial concentrations of reactants. The follow

lora16 [44]

Answer:

Rate constant of the reaction is $3.3\times 10^{-3} M^{-2} s^{-1}$ .

Explanation:

A + B + C → D + E

Let the balanced reaction be ;

aA + bB + cC → dD + eE

Expression of rate law of the reaction will be written as:

$R=k[A]^a[B]^b[C]^c$

Rate(R) of the reaction in trail 1 ,when :

$[A]=0.30 M,[B]=0.30 M,[C]=0.30 M$

$R=9.0\times 10^{-5} M/s$

$9.0\times 10^{-5} M/s=k[0.30 M]^a[0.30 M]^b[0.30 M]^c$ ...[1]

Rate(R) of the reaction in trail 2 ,when :

$[A]=0.30 M,[B]=0.30 M,[C]=0.90 M$

$R=2.7\times 10^{-4} M/s$

$2.7\times 10^{-4} M/s=k[0.30 M]^a[0.30 M]^b[0.90 M]^c$ ...[2]

Rate(R) of the reaction in trail 3 ,when :

$[A]=0.60 M,[B]=0.30 M,[C]=0.30 M$

$R=3.6\times 10^{-4} M/s$

$3.6\times 10^{-4} M/s=k[0.60 M]^a[0.30 M]^b[0.30 M]^c$ ...[3]

Rate(R) of the reaction in trail 4 ,when :

$[A]=0.60 M,[B]=0.60 M,[C]=0.30 M$

$R=3.6\times 10^{-4} M/s$

$3.6\times 10^{-4} M/s=k[0.60 M]^a[0.60 M]^b[0.30 M]^c$ ...[4]

By [1] ÷ [2], we get value of c ;

c = 1

By [3] ÷ [4], we get value of b ;

b = 0

By [2] ÷ [3], we get value of a ;

a = 2

Rate law of reaction is :

$R=k[A]^2[B]^0[C]^1$

Rate constant of the reaction = k

$9.0\times 10^{-5} M/s=k[0.30 M]^2[0.30 M]^0[0.30 M]^1$

$k=\frac{9.0\times 10^{-5} M/s}{[0.30 M]^2[0.30 M]^0[0.30 M]^1}$

$k=3.3\times 10^{-3} M^{-2} s^{-1}$
