Nernst equation

reactant molecule, which is referred as unimolecular step. Also there may be a single collision between two molecules, which is referred as a bimolecular step. It should be noted that majority of the reactions that are written as a single reaction equation actually consists of a series of elementary steps or process. The main objectives for the study of chemical kinetics are: (a) To analyze the sequence of elementary steps giving rise…

Experiment 4: Kinetics of Nucleophilic Substitutions 1. Determine the effect of varying [OH-] on the rate of the reaction. To do this, you should complete the following table: Experiment [tBuCl]0 (M) [OH-]0 (M) Time (s) Reaction rate (M/s) Rate constant (s-1) 1 0.03 0.003 65 4.89 · 10-5 1.62 · 10-3 2 0.03 0.006 213 3.15 · 10-5 1.05 · 10-3 3 0.03 0.009 362 2.96 · 10-5 9.85 · 10-4 What is the dependence of [OH-] on the rate law? The effect of the increased or…

This report gives an information which is related to the reaction between acidified potassium iodide and hydrogen peroxide. Before calculating the rate of this reaction, the reaction will be carried out 3 times and values will be got. A special timer will be used to measure the time. It could be expected and argued that each time will be able differ from the others in each reaction and it can be explained by changing the quantity of hydrogen peroxide. At the final, it will be obviously observed…

The reaction between sodium thiosulphate and hydrochloric acid forms the word / chemical equation below: sodium thiosulphate + hydrochloric acid -> sulfur dioxide + sulfur + water + sodium chloride Na2S2O3 (aq) + 2HCl (aq) -> SO2(aq) + S(s) + H2O(l) + 2NaCl (aq) When sodium thiosulphate reacts with diluted hydrochloric acid, a mixture of…

could easily colonize the galaxy. Nevertheless, with no physical relics, chemical traces, or biological influences suggest the existence of any alternate life form, many may assume that there is not intelligent life beyond Earth. Beyond the Drake Equation and much speculation from the scientific world, no evidence suggests that extraterrestrials have visited Earth or have attempted communication. Without any evidence, accordingly, scientists assume that the resolution of the Fermi Paradox must…

1. Iodide proved to be the more reactive nucleophile in this reaction. This nucleophile was faster than Chloride, because on the periodic table, Iodine has a bigger atomic size, while Chlorine has the higher electronegativity, but size trumps electronegativity, as according to ARIO rules. This means that Iodine is more acidic than Chlorine, which means that in the reaction, the Iodide could displace the Bromine from the 1-bromooctane, because it has a bigger size, much faster than the Chloride,…

Chemical change is any change that results in the formation of new chemical substances. Chemical changes take place on the molecular level. Another way to think of it is that a chemical change accompanies a chemical reaction. To find if a Chemical Change is occurring you need to determine whether a new substance has formed because of the change. If a new substance has been produced, then a chemical change has occurred. The new substance formed in a chemical change could be a solid, liquid or…

The solution of the Frank and Doris race problem looked to be simple at first. Although Doris speed began faster, Frank gained speed and passed her and thus seemed to be the winner of the race. After looking more closely at the problem I discovered this was not quite the case. I first sketched Frank and Doris given values onto the one Velocity-Time graph. Originally looking at this graph, it looks as if Frank passes Doris at 10 seconds, because that is when his speed becomes greater than Doris’s…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…

Mood in the Cold Equations Sometimes, even the most innocent and smallest of mistakes can have a drastic effect on things. Since space is pretty much the full extent of human exploration, small mistakes almost always have a very drastic effect. In the short story “The Cold Equations” by Tom Godwin, he creates an intense and tragic mood, by foreshadowing the inevitability of Marilyn’s death, even when she was innocent and…
