In our previous post, we looked at the overview of the rates of chemical reactions, where we studied the concepts and factors that affect the rates of reactions. In this post, we will be studying the rate law and the different orders of reaction, and how to determine them. Rate Law Consider the reaction:             mA + nB ----> Products The rate law states that the rate of a reaction is directly proportional to the active masses of the reactants. This implies that the concentration of the reacting species will determine how fast and how far a reaction can go. Using the above equation, the rate law can be expressed as:             rate & [A]^m[B]^n ..........(i)             rate = k[A]^m[B]^n ..........(ii) where, [A] = concentration of reactant A [B] = concentration of reactant B    & = sign ...

By Charles Offiong A few days ago, I was discussing with a childhood friend of mine, who also doubled as my classmate. Our subject of discussion was the state and quality of our education vis-a-vis what was obtained in our days. We were lucky to attend one of the foremost secondary schools in Nigeria, the Hope Waddell Training Institution, Calabar, founded in 1895, which prided itself as the oldest in South-Eastern Nigeria and one of the best in West Africa. Apart from her, our first generation universities were ranked among the best in Africa. However, considering the current circumstances, it will be foolhardy of me to presume that my alma mater and those other institutions still maintain these bragging rights... The importance of education to our national development and its need to occupy the pole position of any government cannot be overemphasized. The talk about the declining standards of the Nigerian education is what the blind had seen the dumb told the deaf, so it is no long...
