When the temperature is high and change in entropy is positive.
Answer:
![k=8.63x10^{-8}\frac{1}{M*s}](https://tex.z-dn.net/?f=k%3D8.63x10%5E%7B-8%7D%5Cfrac%7B1%7D%7BM%2As%7D)
Explanation:
Hello!
In this case, since the differential rate law of a second-order reaction is:
![\frac{dC_A}{dt}=-kC_A^2](https://tex.z-dn.net/?f=%5Cfrac%7BdC_A%7D%7Bdt%7D%3D-kC_A%5E2)
Whereas A stands for NOCl and the corresponding integrated rate law is:
![\frac{1}{C_A} =kt+\frac{1}{C_A_0}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BC_A%7D%20%3Dkt%2B%5Cfrac%7B1%7D%7BC_A_0%7D)
Thus, since we know the concentrations and the elapsed time, we compute the rate constant as shown below:
![k=( \frac{1}{C_A}-\frac{1}{C_A_0} )/t\\\\k=( \frac{1}{0.83M}-\frac{1}{0.878M} )/763,200s\\\\k=8.63x10^{-8}\frac{1}{M*s}](https://tex.z-dn.net/?f=k%3D%28%20%5Cfrac%7B1%7D%7BC_A%7D-%5Cfrac%7B1%7D%7BC_A_0%7D%20%29%2Ft%5C%5C%5C%5Ck%3D%28%20%5Cfrac%7B1%7D%7B0.83M%7D-%5Cfrac%7B1%7D%7B0.878M%7D%20%29%2F763%2C200s%5C%5C%5C%5Ck%3D8.63x10%5E%7B-8%7D%5Cfrac%7B1%7D%7BM%2As%7D)

Answer:
Extensive properties depend on de mass, intensive properties not.
Explanation:
The extensive properties depend on the mass and change with the addition or reducction of the mass.
The intensive properties dont depend on the mass. For example: temperature.
I hope I help you.
Metal smelting plants are made to release and remove impurities from metal. The ore is removed through several different processes and in doing so releases the energy from such work and dust and minerals that are removed from the ore itself. Refer below \/ for the needed energy in these processes
carbon in the coal or charcoal used releases vast amounts of CO2 into the atmosphere which is causes a buildup in the ozone and sunlight when reflected off the earth and back into the carbon saturated ozone layer causes what we call the greenhouse effect. Carbon Dioxide is therefore referred to as a greenhouse gas
