Factors Affecting Reaction Rate Bob Jones Josh October 2‚ 2014 Period 3 Introduction: In reference to the collision theory‚ molecules act as small spheres that collide and bounce off each other‚ transferring energy among themselves when the collide. In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include the concentration

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

reaction with the Acetic Acid at 50% as a higher concentration will cause a reaction rate to increase faster. I know the data supports the rate of reaction theory because‚ Graph #1 shows an increase in temperature from an average reactants temperature of 21.09 °C to an average activated complex temperature of 22.39 °C. This is a support piece of evidence that increase in concentration of an acid will cause the rate of reaction itself to expedite. Evaluation: By making my controlled variable stay at

Exchange rate is how much a currency worth in terms of other currency. If currency is free floating‚ which allows the exchange rate vary against other currencies determined by the market forces of supply and demand. Some countries may use fixed/pegged exchange rate system to stabilize the exchange rate. Linked

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

Science: Abstract: This investigation is to show the raspatory and circulatory systems in deeper meaning. It also explains the reasons for why breathing and heart rate becomes higher during physical activity‚ and if there are any differences between female and males. This experiment shows the biological principles‚ and how to record and produce data of a quality standard. Introduction: Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar

magna’s Heart Rate Abstract: Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold‚ its heart rate will lower. When the animal is warmer‚ the heart rate will raise
