Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Dementia awareness -CU238P What is dementia? Dementia is a gradual loss of brain functions. The most common form of dementia is caused by Alzheimer’s disease but there are many other forms of dementia including: alcohol related dememtias‚vascular dementia‚ frontotemporal dementias and Lewy body dementia. Key functions of the brain that are affected by dementia. Each case of dementia is different. The area of the brain affected will depend on the type of dementia. Dementia can affect every

Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.4 2. At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No‚ the pH level of the blood did not change during normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes‚ the pH level was always within the normal range for human body. 6. Did the PCO2 level change during the course of normal

Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare
