To investigate the effect that surface area has on the rate of reaction

Aim: To investigate the effect of change magnitude rebel landing field on the score of reaction. Background information: hydrogen whiten is a chemical substance that consists of hydrogen and oxygen. Its chemical design is H O . It is a colourless, syrupy liquid that has a sharp odour. It is unstable. Peroxidase is an enzyme which catalyses the reaction. Catalase is an enzyme present in the cells of plants and animals. It is an aerobic (requires oxygen) bacteria. It promotes the conversion of hydrogen peroxide, a potentiall(a)y hurtful oxidising agent to water and molecule oxygen. Catalase likewise uses hydrogen peroxide to oxidise toxins. It is located in a cell organelle called the peroxisome. Catalase is a globular protein molecule that is give in all living cells. A globular protein is a protein with its molecules curled up into a ball shape. All enzymes have an dynamical site. This is where other molecule(s) batch bind.         Enzymes are biolog ical catalysts that speed up chemical reactions, without existence utilise up or changed. Reactions bay window be ideal at different rates. The rate of reaction is measured by observing how quickly reactants are used up or how quickly products are forming. The more delicately divided the solid is, the faster the reaction happens. Hypothesis: The high the surface area to volume ratio the higher the rate of reaction. Variables: The independent variable is the surface area. The dependent variable is the nitty-gritty of oxygen produced. The controlled variables include: Ø          deal should be constant Ø          standard of hydrogen peroxide Ø         Amount of water Ø         Temperature Ø         Time Ø          typewrite of liver.

Apparatus: Ø          coloured samples Ø         Syringe Ø         Beaker Ø         Measuring cylinder Ø         water system Ø         Rubber tubing Ø         Beehive shelf Ø         2 riposte stands Ø         Hydrogen peroxide Ø         Test tubes Method: 1. Set up equipment 2.fill up a... This appears to be another well planned and nicely documented experiment. You have succeeded in investigating the effect of increasing surface area on the rate of reaction. Nice hypothesize! If you want to get a full essay, order it on our website: OrderCustomPap er.com
