of Changing the surface area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area increases the rate

In the article" From Stone Age To Phone Age "‚ author Barbara Ehrereich argues that all cell phones serve as a status symbol‚ thus presenting mankind ’s selfish attempt to "showboat" their level of importance. By publicly engaging in meaningless conversations individuals are able to obtain admirer ’s jealously; thus portraying that the on-lookers are lonely because of their absence of a cellular phone or lack of received calls. In fact since primal times it has been a tendency of humans to compete

What are some benefits or limitations of the alternative technology regarding economics? (What will it cost to purchase‚ re-fuel‚ launch‚ educate and distribute?) Benefits. No pollution: A great benefit of using Hydrogen fuel cells is that they give off no pollution‚ and in fact produce pure water as a byproduct. Even though currently engineers are concentrating on producing hydrogen from natural gas‚ it will be for a short-term. Scientists are planning to have renewable environmentally-friendly

different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing position in the water. But how does the surface area of an object

Outline the roles of membrane at the surface of the cell The plasma membrane encloses the cell‚ defines it boundaries and maintains the essential differences between the cytosol and the extra-cellular environment. The separation of the internal and external environment maintains a constant internal environment which is essential for the cell to function efficiently. Membrane receptors can interact with specific molecules corresponding to stimuli such as hormones to generate a signal cascade which

the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size of the surface area to volume ratio of the solid reactant.

Do your results support your hypothesis‚ use date from your table and graph to support your answer‚ you should also identify any anomalous results. My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion

Figure 1. Average Mass Specific Surface Area for Three Fish. Error bars represent standard deviation from the mean. The graph represents the mass specific gill surface area for a sample size of 6 gill arches for each of the 4 lab sections (n=24). For Mackerel‚ the mass specific gill surface area was 13.62 cm2/kg. For Whiting‚ this value was 9.34 cm2/kg. Lastly‚ for flounder this value was 2.93 cm2/kg. Results: The three different species of fish‚ Mackerel‚ Whiting‚ and Flounder‚ have distinct
