reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher from Greece suggested that matter is made up of tiny particles too small to be seen. He thought that if you kept cutting a substance into smaller and smaller pieces‚ you would eventually come to the smallest possible particles. The rate of a chemical reaction

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 of reaction increases

Determine the equivalent discount rate for a period length of a. Six months. b. One year. c. One month. a. Since 6 months is [pic] of 2 years‚ using our rule [pic] So the equivalent 6 month rate is 4.66%. b. Since one year is half of 2 years [pic] So the equivalent 1 year rate is 9.54%. c. Since

MANAGEMENT OF EXCHANGE RATE RISK EXPOSURE There are number of ways by which exchange rate risk exposure can be managed: - Natural Hedges - Cash Management - Adjusting of Intracompany accounts - International financing hedges and currency hedges through forward contracts‚ futures contracts‚ currency options and currency swaps NATURAL HEDGE - A hedge (risk reduction action) that occurs naturally as a result of a firm’s normal operations. For example‚ revenue received in a foreign

Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide.

countries had a very low life expectancy and a very high mortality rate‚ specifically‚ infant mortality rate. The increased mortality rate and the low life expectancy is caused by the poverty and the poor living conditions in which the people live in. The poor conditions in which they live in cause them to have poor health and lack sanitation. Lack of sanitation leading to poor health is the main explanation to high infant mortality rates and low life expectancy. Disease is a huge factor that contributes

Introduction: Basal Metabolic Rate has been defined as the minimum amount of energy needed by an animal to maintain the basic functions of survival (such as breathing). Several factors including age‚ gender‚ weight‚ and exercise affect the BMR. "BMR increases with increasing muscle tissue" therefore‚ exercising will enhance BMR while with increasing age‚ BMR is reduced (Scott‚ 2008). Also gender differences exist between males and females; it has been shown that males have higher BMRs
