Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

this experiment‚ I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature‚ the faster the reaction rate. This is due to the kinetic theory. The more heat that is given to matter‚ the faster the particles move. This happens in the acid‚ so the faster the particles move‚ the faster the reaction rate due to more collisions between the marble chips and the acid

positive relationship between catalase concentration and the rate of reaction. This means when catalase concentration increases‚ the rate of reaction also increases. In other words‚ at 20% catalase concentration‚ the rate of reaction was only 4.220 mm/s while at 100% catalase concentration‚ the rate of reaction was 7.704 mm/s. This proves the positive correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme concentration increases‚ there are more enzymes available

EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage

Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance
