Answer:
C) It has a constant average kinetic energy
Explanation:
The average kinetic energy of the particles in a gas is directly proportional to the temperature of the gas, according to the equation.
k is the Boltzmann's constant
T is the absolute temperature of the gas
Therefore, temperature of a gas is a measure of the average kinetic energy of the particles.
In this problem, we are told that the gas is at constant temperature (and volume): therefore, according to the previous equation, this means that the average kinetic energy is also constant.
Answer:
Si una reacción química libera energía, se llama reacción exotérmica. El ejemplo más común es la combustión, en la cual la energía se manifiesta en forma de calor y luz. Si, por el contrario, la reacción química requiere energía del medio para efectuarse, recibe el nombre de reacción endotérmica.

Answer: The order with respect to 
is 1.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![Rate=k[NH_4^+]^x[NO_2^-]^y](https://tex.z-dn.net/?f=Rate%3Dk%5BNH_4%5E%2B%5D%5Ex%5BNO_2%5E-%5D%5Ey)
k= rate constant
x = order with respect to
y = order with respect to A
n = x+y = Total order
From trial 1: ![3.2\times 10^{-3}=k[0.0100]^x[0.200]^y](https://tex.z-dn.net/?f=3.2%5Ctimes%2010%5E%7B-3%7D%3Dk%5B0.0100%5D%5Ex%5B0.200%5D%5Ey)
(1)
From trial 2: ![6.4\times 10^{-3}=k[0.0200]^x[0.200]^y](https://tex.z-dn.net/?f=6.4%5Ctimes%2010%5E%7B-3%7D%3Dk%5B0.0200%5D%5Ex%5B0.200%5D%5Ey)
(2)
Dividing 2 by 1 :![\frac{6.4\times 10^{-3}}{3.2\times 10^{-3}}=\frac{k[0.0100]^x[0.2000]^y}{k[0.0200]^x[0.200]^y}](https://tex.z-dn.net/?f=%5Cfrac%7B6.4%5Ctimes%2010%5E%7B-3%7D%7D%7B3.2%5Ctimes%2010%5E%7B-3%7D%7D%3D%5Cfrac%7Bk%5B0.0100%5D%5Ex%5B0.2000%5D%5Ey%7D%7Bk%5B0.0200%5D%5Ex%5B0.200%5D%5Ey%7D)
therefore x= 1
Thus order with respect to is 1.
