Bingying Jiang CHM 152ll April 25‚ 2013 Some Factors that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the

Chapter 1 INTRODUCTION 1.0 BACKGROUND There are enormous opportunities for savings in the tourism division of Malaysia. The Malaysia government is totally dedicated to the development of this division. Over the last 12 years‚ wide promotional campaigns have been engineered both locally and overseas to attract tourists from around the world. Even though the economic slowdown‚ the tourism industry is still remains strong. Today‚ Malaysia is one of the most popular tourist destinations in Asia

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting

I am going to investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes‚ current changes‚ as Ohm’s law: I = V/R. If one part of an equation changes‚ the equal must be done to the opposite side. To detect how resistance affects current‚ I must first discover what factors affect resistance. These factors are: · Length of the wire if a wire is longer; there are more particles for electrons to move through‚ and therefore more resistance

Some children may suffer from or be more prone to a condition that may make progress difficult. Some conditions that children are born with such as diabetes or a blood condition affect children from early on and have sever ramifications on their lives from birth. Other conditions may appear later‚ such as asthma‚ which children are more susceptible to if they live in areas where the air condition is poor‚ they live in damp conditions or whose parents smoke. These conditions and many others have an

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

What Factors Affect AM And FM Radio Reception? Background Information Communications are carried by waves. One type of communication is AM and FM radio. AM and FM radio’s use radio waves. A radio wave is an electromagnetic wave propagated by an antenna at various frequencies. In AM (amplitude modulated) radio waves‚ the audio signal changes the amplitude of the carrier wave. In FM (frequency modulated) radio waves‚ the audio signal changes the frequency of the carrier wave. Australia’s broadcast

In society today there are many social-economic factors that may influence an individual’s health and illness. Thinking about health‚ it is acceptable in today’s society that health is not a fixed thing. More aches and pains come as people get older and this is accepted as a normal part of ageing‚ but these aches and pains for a younger person are not accepted as normal. "It has been argued by many sociologists that what has been considered to be normal in one society or in one period of history
