reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes too high. This is due to the fact that enzymes become denatured at high temperatures. Denaturation occurs when the shape of an enzyme is altered and so loses it ability to function.

Interpretation of Data When looking at my results i can safely say that the change in HCl concentration does affect the rate of reaction with the Calcium carbonate pebbles. The relationship between the change in HCl and reaction rate can be seen in the graph and raw data table presented above. If you compare the lowest concentration with the highest concentration you’d be able to see that there is a very large contrast between their averages. The average gas production of 0.1M HCl was 0.00693 kPa/s

The Effect of Different Genres of Music on the Growth Rate of Garden Cress AIM The purpose of this experiment is to explore upon the possible correlation between musical stimulus and the growth rate of Lepidium sativum‚ commonly known as Garden Cress. It also aims to discover which genre amongst classical‚ jazz‚ and rock has the most beneficial effect on its growth rate. PERSONAL ENGAGEMENT The Garden Cress plant‚ better known by its botanical name Lepidium sativum‚ is amongst the many plants that

Analysis • Error Bars Analysis Evaluation • Improvement Assessment • Improved Experiment. • Reliability References Introduction: For this data analysis project‚ I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that

which pertains to how much energy is needed for chemical reactions to take place. Enzymes also known as catalysts is one of the main factors in producing energy in individual’s bodies. The experiment conducted was to test how different temperatures effected the catabolizing of fungal and bacterial amylase‚ as well as the optimal temperature needed for the enzyme to correlate with the bacteria and fungi. The enzyme’s break down within the starch was observed through different temperatures and time periods

point happens when a substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand factors

What affect does exercise have on these parts of your body? Heart‚ Lungs‚ Muscles‚ Joints and Body Temperature? After exercise‚ you’ll find your body experiences immediate and more gradual effects. The minute you start training‚ you’ll notice more frequent muscle contraction‚ raised body temperature and pulse‚ and deeper breathing known as tidal volume. Longer-term effects occur as the body adapts to regular exercise‚ including your heart getting larger‚ bones becoming denser and the vital capacity

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they
