Composting is a technique that allows biodegradable materials of urban, domestic and industrial origin to be degraded to form humus, a type of soil that is very fertile and extremely rich in micronutrients.
These biodegradable materials are materials of organic origin, such as food scraps, fruit peels, pieces of vegetables, among others. As the domestic environment generates a large amount of organic waste, composting in this environment is very favorable, and it can generate a very rich soil to be used in the garden, in vegetables, among other places.
Hope this helps :)
Speed and velocity is a scalar and vector quantity of a similar parameter, respectively. They both refer to how fast an object moves. However, the speed only has to do with the magnitude. The velocity takes into account the sign which indicates the direction of the movement. For example, the value is -5 m/s. The speed is 5 m/s, but the velocity is 5 m/s moving downwards because the negative sign denotes downward movement or movement to the left.
Answer:
The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
![R=k[C_4H_6]^2](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5E2)
Explanation:
The rate of the reaction ;
![R=k[C_4H_6]^x](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5Ex)
As given in the question , that graph of time verses ![\frac{1}{[C_4H_6]}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BC_4H_6%5D%7D)
was linear but plots of ![[C_4H_6]](https://tex.z-dn.net/?f=%5BC_4H_6%5D)
or ![\ln[C_4H_6]](https://tex.z-dn.net/?f=%5Cln%5BC_4H_6%5D)
was curved.
Generally:
Graph of time verses ![[concentration]](https://tex.z-dn.net/?f=%5Bconcentration%5D)
for zero order reaction is linear with negative slope.
Graph of time verses ![\ln [concentration]](https://tex.z-dn.net/?f=%5Cln%20%5Bconcentration%5D)
for secon order reaction is linear with negative slope.
Graph of time verses ![\frac{1}{[concentration]}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Bconcentration%5D%7D)
for secon order reaction is linear with positive slope.
So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
