    The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important

    I think that Jane Elliot was a woman before her time. What she put together to teach the children about discrimination was brilliant. I not only watched the first and second parts in class‚ I watched all six parts on You Tube. I laughed and cried watching all six parts. I see that just putting the idea into ones mind can make things happen. I think the most upsetting part of this experiment is that if you place children in the subordinate group they immediately did poorly.I feel that more people

    Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

    affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the experiment. The Manipulated variable will also be the water‚ since I will be changing

    shifts to the right hand side to make more until eventually all of the acid is able to react. This does‚ however‚ absorb energy as bonds are being broken to dissociate the weak acid. CH3COOH H+(aq) + CH3COO-(aq) approx 99% approx 1% Conductivity Any solution’s ability to conduct electricity is conditioned by the concentration of ions it contains. A strong acid has more ions than a weak one‚ and so it’s solution will be a better electrical conductor than a weak acid. The same
