I think it is A. The reaction rates can change.
I think we all know that B. and C. are incorrect, but I took a science lesson about this and it specifically said that on a graph of a rate, a curved line is NOT constant, meaning it is possible to not be constant.
Answer:
is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas
for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.
Answer:
Explanation:
Rate laws are mathematical expressions which define the relationship that exists between the rate of a chemical reaction and the concentration of the reacting components. Rate laws take the following form:
![rate = k [A]^{x} [B]^{y} [C]^{z}](https://tex.z-dn.net/?f=rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D%20%5BC%5D%5E%7Bz%7D)
...
where k = rate constant
[A], [C] and [C] represent the molar concentrations of the reactants
k, x, y, and z are determined experimentally by observing how the rate of reaction changes with the concentrations of the reactants.
If x=1, the reaction is first order for [A]. Also, if y=2, the reaction is second order for [B] and so on...
The overall order of the reaction is the sum of the orders with respect to each reactant. Therefore, the overall order of the reaction is x+y+z.
