Answer: For the elementary reaction
the molecularity of the reaction is 2, and the rate law is rate = ![k[NO_3]^1[CO]^1](https://tex.z-dn.net/?f=k%5BNO_3%5D%5E1%5BCO%5D%5E1)
Explanation:
Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.
Elementary reactions are defined as the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical reaction.
Molecularity of the reaction is defined as the number of atoms, ions or molecules that must colloid with one another simultaneously so as to result into a chemical reaction. Thus it can never be fractional.
For elementary reaction
, molecularity is 2 and rate law is ![rate=k[NO_3]^1[CO]^1](https://tex.z-dn.net/?f=rate%3Dk%5BNO_3%5D%5E1%5BCO%5D%5E1)
The answer is A) Scientific Law
Answer:
"3. Energy can either be destroyed or created. Its goes from one form to another."
Explanation:
The third answer choice, "3. Energy can either be destroyed or created. Its goes from one form to another.
" is related to the Law of Conservation of Energy from thermodynamics. Is it not a postulate of the Kinetic Molecular Theory.
<u>"1. Average Kinetic Energy of the system is a measure of the temperature of the system."</u>
Postulate of Kinetic Molecular Theory 
- The average kinetic energy of the system is measured by its temperature and nothing else
<u>"2. Energy is conserved in the collisions between gas molecules.."</u>
Postulate of Kinetic Molecular Theory 
- All collisions between gas molecules are perfectly elastic, meaning no energy is lost
<u>"3. Energy can either be destroyed or created. Its goes from one form to another.</u>
<u />
NOT a Postulate of Kinetic Molecular Theory
- Related to Conservation of Energy from thermodynamics
<u>"4. Gases travel in straight line until they collide with other gas molecules"</u>
Postulate of Kinetic Molecular Theory 
- All gas molecules will travel in a straight line until they collide with other gas molecules or some object (e.g. a container)
