enzyme activity and enzyme catalyse works better in neutral solution. The data overall shows that catalyses react slowest in acid solution and react fastest in the neutral solution. There is no reaction in ph 2 solution happened and the reaction in ph 4 solution is obviously slower than that in neutral solution and basic solution. In Graph #2‚ the highest point of reaction rate is at pH 7 and the lowest point of reaction rate is at pH 2. It shows that when pH is far from the optimum ph for enzyme activity

purpose of this experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model

hate‚ jealously‚ pride‚ and trickery are thoroughly developed in the play of Othello to enable the audience to view the characters and also themselves. The Shakespearean tragedy of Othello was written in a time of great racial tensions in England. According to Eldred Jones‚ in 1600 just three years before Othello was written‚ Queen Elizabeth proclaimed an Edict for the Transportation of all "negars and blackmoores" out of the country ("Othello- An Interpretation" Critical Essays 39). It is in this atmosphere

the inverse. Frankenstein made a being and dismissed it directly after it sprung up. He was brutal towards the animal all through the novel on the grounds that notwithstanding when the animal needed to search for peace with a sidekick‚ Frankenstein wouldn’t concede this desire. Conversely‚ the animal was grim and monstrous outwardly however had all the more an accommodating nature than Frankenstein. The animal was benevolent and delicate before Frankenstein’s activities made him change his heart and

Animal Farm by George Orwell is an allegory that represent the Russian Revolution. The key point in Animal Farm‚ language is a powerful tool that can be used in a positive or negative way‚ and can work to one’s advantage or result in serious consequences. The pigs make others work extremely hard‚ while they sit back and rest. For example‚ “Now comrades...to the hayfield! Let us make it a point of honour to get in the harvest more quickly than Jones and his men could do.” (Orwell‚ 24) Later in the

Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

so deeply ingrained and powerful that it cancels out a person’s ability to behave morally‚ ethically‚ or even sympathetically. In 1963 Milgram carried out an experiment. He hypothesized that individuals who would never intentionally cause someone physical harm would do so if ordered by a powerful authority figure. To carry out the experiment‚ Milgram designed a shock generator- a large electronic device with 30 switches labeled with voltage levels from 30 volts increasing at 15-volt intervals to

The Industrial Revolution had many effects on the way of life and countries growth afterwards. Some negative effects include‚ unfair working conditions‚ union strikes‚ pollution and child labor. A few of the most important positive effects of the I.R. were‚ unions formed‚ new transportation‚ the need for raw materials and new markets‚ and Imperialism. These effects lead directly into imperialism and the need to imperialize. The Industrial Revolution motivated European nations to compete for overseas
