Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration 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 faster the rate of the reaction. However‚ in order for the

Effects of Raising Interest Rates If a central bank increases the base rate‚ this tends to increase all major interest rates in the economy. This means interest rates for both savers and borrowers will increase. Higher interest rates will have various economic effects: 1. Increases the cost of borrowing. Interest payments on credit cards and loans will be more expensive. Therefore this discourages people from borrowing and saving. People who already have loans will have less disposable income

Mortality rate is a measure of the number of deaths (in general‚ or due to a specific cause) in a population‚ scaled to the size of that population‚ per unit of time. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus‚ a mortality rate of 9.5 (out of 1000) in a population of 1‚000 would mean 9.5 deaths per year in that entire population‚ or 0.95% out of the total. It is distinct from morbidity rate‚ which refers to the number of individuals in poor health

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

HARMFUL AND DETRIMENTAL EFFECTS IN CELLPHONE USAGE In recent years‚ mobile telecommunication systems have grown significantly‚ to the point where more than a sixth of the world’s population uses mobile phones. By the end of 2004‚ more than a billion subscribers across more than 200 countries were estimated to be using mobile phones The development of mobile communications has moved rapidly. In the 1980s‚ first generation mobile phones‚ using analogue technology‚ allowed the transmission of
