LABORATORY 3 The Effect of Temperature on the Rate of PNPP Hydrolysis Partners: Shelby Cruickshanks Alexis Williamson Introduction Most of the chemical reactions‚ which occur throughout our bodies‚ would proceed at a much slower rate of reaction without the presence of an enzyme. Cells can not wait for centuries for molecules to break down‚ if they waited for that‚ there would be no way for the organism to obtain energy or in turn survive. This is where biological catalyst comes into

Internal Assessment: Rate of Evaporation Ann George Mr. Frias/4th Period Wheeler High School Research Question How will changing the molar mass of alcohol affect the rate of evaporation‚ represented by the change in temperature over time‚ measured using a temperature probe? Research/Abstract Alcohol is an organic compound in which the hydroxyl functional group‚ OH‚ is bound to a carbon atom. Its carbon center should be saturated; it should have single bonds to three other atoms. The different types

Since the 1900’s‚ the overall death rate of the population in Britain has decreased. For males‚ the death rate has dropped from 25829 in 1901 to a mere 8477 in 2000. The rate fell from 21705 to 5679 within the same period of time for females. It was noted that death rates increased during flu epidemics as well as in cold and hot weather. For example‚ about 200 000 people died in the year 1918 due to the influenza epidemic. Nowadays‚ more people die after the age of 65 while in the early 1900’s‚ only

Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered
